In reply to THE.WALRUS:
either get a hero 2 or if you can find one for the money, a hero 3 silver edition
yes the hero 3 black is expensive, but it's probably more aimed at the pro-sumer market. the silver is basically the hero 2 in the new, smaller form factor.
i think all the old mounts work with the new hero 3 range so you still have all those options.
even the hero hd (hero 3 white) does 720p 50/60fps) or 1080p (25/30fps) (that's PAL/NTSC on the frame rates)
if you do go gopro, make sure you buy a decent memory card, slow ones can cause the camera to crash or freeze up... also upgrade the firmware on what ever you buy to get it working as well as possible.
BUT, there are other choices out there so might be worth looking at contour / drift / sony ar?
i have the hero HD with a few accessories and it's mostly been pretty damn good
