My old $40 Nashbar bargain HRM is about to bite the dust, and I need your suggestions. On another post I saw a graph from the Polar 720i, that one looks good but this is what I need:
-HRM, altitude (vertical climbed to be specific), and computer interface.
Would also be nice to have:
-Compass, cycle speed.
I found the 720i here for $287, is that a good price?
