I am looking to pick up a camera. Can you share your experience with the models you have used? As far as I know, there are the helmet mounted, head strapped and handle bar mounted types. Advantages/disadvantages? Ease of installation?

Waterproof-ness is a definite plus. If I can use it for other purposes like skiing, that would be great.

Here are the 2 I have found:

Contour Roam $130:

Mobius ActionCam $75:

I also heard goPro is popular, but they seem a little pricy.
