I just got a CatEye Astrale. It's got all the basic functions I need, including cadence. I'm a happy biker now.

The only gripes I have are: the wiring is too short, and the fact that the clamps were designed for road bikes, not MTBs.

I've been told that CatEye has had few problems with changing technology and changing mounts ... they keep their original mounts with new models. This is the main reason why I went with CatEye.
