I looked at a PT on eBay that was going for $400, but it was just too much of a stretch for me right now. I thought, too, that (as you said) I can sell this one down the road if/when I upgrade (and that upgrade might include a bike - just wishing!).
Question - I have heartrate and cadence with my Garmin 305 - and I WANT to keep using that. Is it feasible to use the Powertap just for power and use the Garmin for the other data? Of course, that means having two devices in front of me, but no big whoop.
And, Shovel? THANK YOU!!!
