I have the current top model ContourHD 1080p. It has beautiful video quality, is small and very light and you can wear it on your helmet if you want to. The switch is a big slider which works with gloves on, it has a rotatable lens so you can level the picture once mounted and it also has a laser pointer on each side of the lens to help this. It comes with a 2gb memory card. Downsides are that it takes MicroSD cards which are hard to find and expensive in large capacity 6 class sizes and the microphone is worse than useless. If you use a helmet mount you will get nothing but wind noise. Follow the link in my sig line to see some videos; all done at 720p low-res.
Having said all that, buy the GoPro. It is a bit cheaper than the Contour and a far better camera for bike work, has better mounting hardware, uses cheaper SD cards, the mic works and the video quality is excellent. If you don't need HD then you can get the 720p versions for considerably less.
