My needs are basic: given that I mostly use MapMyRide (etc) to measure my commuting or training routes, my primary need is the autostart/stop for timing purposes (I don't want to fuss with a cellphone or stopwatch for this).

My only other needs are: inexpensive and availability of mounts for other bikes (although, if the cyclocomputer is cheap enough, I may not worry about other mounts).

I don't care if it is wired or wireless although, wireless versions of wired models tend to be more expensive.

Suggestions welcome, please!!!
