Powermeter advice on a budget

I frequently read the DC Rainmaker reviews. They seem thorough and fairly unbiased.
Essentially, if new, I'm between a 4iiii left only unit at $400 or a new non-direct measure Powerpod.
If used, I'd either get a used 4iiii left only OR a set of Garmin pedal for one side only.
I don't have the talent nor ever will to justify $800 or more on a power meter. I can train with power on a trainer at the gym at my workplace.
I don't need it to be super accurate, just somewhat consistent.
DC reviewed the Powerpod fairly well and the data followed direct measure units pretty well. But, I somehow find the concept a bit......lame (uninteresting, silly). But......they claim to have their own pedal stroke analysis.....somehow. Also you could I guess hope for their upgrade at some point to analyze cD for TT positioning if they agree on an ant+ field for it.
Given I'm no trained pro, I'm sure some tool like that may help for pedal stroke and aero.
My goal is to have a meter to be able to effectively work myself on the road without guessing on effort.
I'm not into expensive stuff as I'll only ever probably hit an ftp of about 250w and 5 min max of maybe 320. Nothing impressive worth blowing $1000 on.
If the Powerpod gets a nod, I'd spend the $300 soon.

Then riding on PE will probably be the best money you can spend
Has dcrainmaker reviewed one of these yet?

There are also whacking great big limitations of single sided systems but if you can pick one up second hand and decide you can't live with those limitations then at least you should be able to sell on for not much loss.
Not sure where you are getting universally panned from?
Main problem is that most of my miles are either commuting or club runs, on neither of which do I really get a chance to target power intervals or otherwise pay that much attention to it, so it mainly just provides some extra data to look at after the ride.
It does beat regular power meters on that though, as it records wind speed and much more accurate elevation than any Garmin can.
Ultimately, there are limitations to the accuracy of the power data, but those limitations are arguably less than single sided meters, and you can make an argument that seeing real time aero data is worth the compromise.
The point of it on the bike is pacing for longer efforts. Also, any future attempts at an Ironman putting out level power for a couple hours is very important. So HRM or just physical exertion won't cut it. I've come to love training on the Cycleops with power. Especially if I do a relay Ironman to get my feet wet in the sport and pull the bike leg. They'll be expecting me to put out optimal for sure for my leg. Also for any dabbling in ITT that I may try at some point.
No votes for 4iiii in that price range?
Thank you for any info there on the Garmin pedals, that is a lot of money for used pedals if people have issues with them.
Not necessarily true. I did a sub six hour ride as part of an Ironman (my 4th triathlon ever, my 1st that wasn't a supersprint and within a year of starting cycling for anything other than transportation) on HR alone. I had done 6 sessions on a turbo beforehand to establish my HR at FTP and just worked off that. Did a 3hr45min run afterwards too, so I can't have gone too far wrong.
It might not work for everyone and if you find power more useful then great, go with that - but don't discount HR out of hand.
I've had my 4iiii single sided for about 4 months.....couldn't be happier. No need to look anywhere else 8)
Yepp, worth bearing in mind that PMs were only available relatively recently and no one can say that Jacques Anquetil, Big Mig, Eddy or Lemond, etc., were censored at TTs before they came along. HRM does have its disadvantages but, if used correctly, it can still offer big benefits for most riders where getting the last x.xx% doesn't really matter.
Sure, HR will drift over a ride but you'll have a feel for how much. If can vary slightly day to day too, but again you often get a feel of this when you do your warm up. For efforts over 10 minutes it's pretty much fine for pacing.
Perceived effort is also key. In the later stages of a interval / race / long ride all that matters is perceived effort. It doesn't matter what any of the numbers on computer says, it's just about what your body and mind can tolerate.
So, if you're short of cash, I'd always say buy things that allow you to train more often or for longer. You'll get a larger performance gain from them (winter clothes, comfy saddle, a winter bike with guards, good lights, etc.).
Obviously, if you have cash to splash, then get a power meter for the data interest. Out of the ones you've suggested I'd get the 4iiii as it seems to have the least reliability issues but I haven't used one myself.
Where power is useful is measuring training load, short duration intervals, accurate fitness tests (in absence of long sheltered climbs). But non of it is essential and it sounds like yo have indoor trainers at the work gym which can be used for this anyway?
Now, if you planning to do other things; aero testing, evaluating TTT pacing, reviewing race performance of multi climb races, or following an incredibly specific training plan; then a power meter would be a worthwhile investment. If that is the case, and you're on a budget, i'd look at the second hand market and either get a crankset or rear wheel device depending on your specific requirements.
Reliability of data: I think both are pretty solid when they work, although it seems that Stages has massive battery issues, which very much put me off buying one!
Price: 4iiii wins hands down, I paid $400+30 (~£347), stages comes in at £360, or if you don't like silver £450 for black.
Data collection: Both use LHS only, but if you go on the 4iiii website you will notice they also do dual sided, so if you change your mind & want to upgrade later on, that should be possible (when they release 105, ultegra etc)
Customer service: Both are pretty good I've heard.
Can't comment on any other comparisons.
I do accept that to some level, given I'll only ever FTP in the 200's for power and never the 300's, that this will be a toy.
I do wonder if for someone only ever up to 250w or maybe 270w ftp if it would be more fun to just use HRM and blow money on wheels instead.
If I'm already at 230w after 1 year of training, that gained me 70w of power in that year WITHOUT a HRM or PM. Just riding and using the gym trainer with power.
If I only want another 20 to 40w, I'm guessing HRM and wheels are easily worth that over another full year of the same level of training volume.
I feel $225 is worth a try.
Too late, it's on it's way along with a proper crankset to match the arm length. All-in, it's $300 US for both. So now the bike has a full matching 105 group including the meter. Except for the aero brakes of course.
I live in the south in the US. So your idea of "cold weather" is probably a little different than mine.
We only get measurable snow once every few years. This 2016/2017 winter my average night-time ride temperature was probably 45 deg F. A cool night ride in winter might be 35 deg F.
Almost never below freezing. If it is, it's only for a week per winter and then you just ride the trainer in the gym.
