GPS or sensor cycle computer up to £150

Hello
I need some help. I want to spend up to £150 and am confused as to which computer to buy. Was going to go for a garmin 500 till I started reading reviews about how it can be inaccurate with current speed and distance.
The main bits I'm after are
Altitude details
Max speed, distance travelled
Then I looked at vdo mc 2.0 which measures altitude by pressing a button so it can read cureent air pressure.
But then I quite liked the idea of the garmin being GPS so I could track my ride.
Has anyone had any experience with these or any other similar devices they would recommend.
Thanks

One of the best bits was when I plugged it in when I got home to Garmin Connect. The info is really good to see. Mapped out etc. Looking forward to when I start riding to work and comparing my times on the same route and looking at where I could push a bit more.

I've just got a Forerunner 410 and find Garmon Connect OK, Strava is much more useful though, I feel.
