Looking to get a wireless cadence monitor, think I have it narrowed down to these. There is a version of the Cateye (410) without the heart monitor, but it only adds $25 (vs $50 or so to add on later) and since the Rox comes with one, thought this was the fairest comparison. The Strada 4xx series looks to be the replacement for the Double wireless.
Cateye is around $110+ tax delivered, Rox about $15 more.
The Wahoo is nice in that you get the other functions of your phone like being able to use cyclemeter and other apps, but it's about $160 for the sensor and computer (I don't want to mount my phone) and doesn't have the heart monitor.
Any opinions or anything else to look at?
GPS support is not important.
