The 2010 cycling season is about to start for me and I am looking at upgrading my cycling computer. I currently use a Polar watch with cadence and speed sensors in addition to the typical heart rate data. In my new system, I am looking to adding GPS data for accurate altitude information, and for tracking my routes. I would also like to add an Power meter. I am currently considering the Garmin Edge 500 cycle computer. The basic Garmin Edge 500 setup tracks distance, speed, location and elevation with high sensitivity GPS. The Edge 500 is compatible with the Ant+ devices, making it easy to expand the system to add heart rate monitor, speed / cadence, and power meters.
