How do you choose & fit susp.forks for a rigid?

I have a rigid Hardrock XC 2005 and want to put a reeeeeaaallly basic set of forks on, just to absorb bumps, purely on a 'comfort' level. I'm confused though...what do I need to look for? The techno spiel means nothing to me! LOL. Also are they easy to fit? (I'm used to stripping and maintaining my own bikes so I am quite capable of undertaking most jobs myself)
This is the full spec of my bike so if anyone could point me in the right direction I'd be very grateful!

Ok you want to look for a 80/100 XC for with V brake bosses, unless you are thinking of changing to disc brakes.

what fork maybe try in the buying section.
any specific tech problems with the fitting ask away."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

I've just changed from rigid Project2s to a set of Maverick SC32s, and it's not such a bad job, plus you can give your headset a service at the same time!
Only thing you can't do in the lounge is re-fit the headset bottom race to the new forks (unless you just happen to have a tube of exactly the right size to hit it with - about 1 3/16"!) - you're local shop can do this in about 11seconds & I can't imagine them charging for it! Although I usually like to ask favours whilst I'm buying something else
Tragically, I photo-documented the whole process, just incase it was handy for someone on here (that, plus it was a momentous day for my bike!); I'll send them over if you like, but it'll be a few days before I get chance.
If you're literally just looking for comfort then I guess it's not such a big decision, but I have to say I've not found that much difference - I'm just going faster for the same battering!
Coil springs are going to be more reactive to the smaller bumps, and probably give you a wider choice at the lower price points as well, so that's a good start. I guess bouncing on a few and picking the ones with the least stiction (the force needed to get them moving - NOT the spring stiffness) is probably the best way to choose for comfort.
If you're not going to thrash them you can err toward a softer spring as well, without worrying about the bottom-out too much.
Hope that helps, as it's long, boring read otherwise!WTD:

Thanks guys, its starting to make more sense!
I'm not planning to fit disks: the bike is going in about a year anyway (when we get a bigger house with a garage we're investing in some really decent bikes) so I'm just after very cheap forks to replace the rigid ones for the time being. I went on a ride with three other people today and all of them had front shocks, as a result they found it easier to shoot over the uneven bits, I had to slow down for fear of breaking my arms...and knees and ended up trailing behind...lol*** 2005 Hardrock XC rigid in 'Dream' silver ***0 -
Just a thought, but plan B (there's a C as well, if you've the patience) could be just fitting a fat - and I really do mean FAT - front tyre, I honestly reckon that will give you as much, if not more, comfort, for less cash, with lots of extra traction as an added bonus.
Rotating weight (as oppose to the additional static weight of the forks) and potential extra drag are the downsides, but something like a 2.4 Continental Mountain King would probably even save you weight!
Halo used to do a 3" front called the Contra, not sure if it's still available, plus the Nokian Gazzalodi(?) and Surly spring to mind.
Other option is get a really good fork & transfer to to your new bike next year - that way your money's not wasted!
One last, but probably much more salient point: Relax! Loosen your grip on the bars, push your elbows out, let your knees go 'baggy' and let the bike move underneath you; a well ridden rigid bike will be within a whisker of a hardtail - or even full-suss - on all but the very roughest of tracks if you can learn to let it run. Then, when you transfer those skills to your next bike you'll be amazing, thrashing all your friends everywhere!
