I'm looking for some advice around quality, mid range bike computers.

I'm after the following features:
- current speed
- average speed
- max speed
- trip distance
- odometer
- time elapsed
- clock
- wireless

The unit will be fitted to a mtb and must be robust enough to cope with offroad riding.

My budget is max US$70. Can anyone recommend in their experience a quality brand and model that fits what I'm after? I've looked at the Topeak Panoram V10, Cateye Strada Wireless RD300W and Cateye Micro Wireless so would welcome comments on them or any other models.
