Ditto to what Susan said..........we LOVE our Garmin. My husband and I both have the Edge 705...........I was going to go for just the 305 but he twisted my arm. He is a gadget guy and wanted all the bells and whistles. I have to admit having the maps capability is very nice when you are on a route and :
1. Don't know really WHERE you are and want to get back home...or
2. Want to know HOW MUCH LONGER til we get to stop or find civilization.

As I am a fairly new road biker (just started in March/April 2008) I can say it REALLY helps motivate me. I want to do the hill faster, have a better cadence, higher heart rate and it does it all. Plus it is always fun to compare past routes that are the same and see your improvement.

Thanks for the info on making sure the senso and magnet are not aligned......we have not had anr problems with them but would rather avoid them at all costs...........
