Garmin E Trex HCX
 

I will have the opportunity to choose the Garmin E Trex HCX GPS unit through an awards program at work. I currently run a Polar that downloads HR, cadence, speed, cals, etc. Has anyone had any experience with this Garmin unit on a bike? Should I get the Ipod instead and get an Edge when my Polar dies (or when I get my $600 economic stimulus check)?
