Garmin 405

I've tried all the Garmins and the 310XT is the best of the bunch.  It's waterproof and no speaker holes, so less sweat corrosion on the electronics.  It is push button and locates satellites quickly.

For what it is worth to anyone:
Due to injury I think I will be doing more running on the treadmill in the near future, whereas I have not done so hardly at all since I got the Garmin 405cx. On the treadmill, I use the foot pod to track distance and time I noticed differences between my Garmin's info and the treadmill's  and so I thought I would calibrate the pod on a local 400m track. Garmin recommends the distance method (800m) but you can also do it with the GPS. I tried doing it both ways and the GPS was more accurate: a little over 1% error compared to around 3%. The GPS was showing accuracy to 18 feet when I started and there aren't too many obstructions.
