I was just sent this cool cam setup from eHelmetCam.com to test out. It is a "bullet cam" with a full featured DVR.
It has a boatload of camera setting options as well as playback, preview etc... for about $400. One of the best things I've noticed so far is little to no "jello-ing" of the video when you hit the harsh chop.
Being a bullet cam style allows you to locate the camera in a lot more creative areas too... which I will be experimenting with
Currently I've got it mounted on my Tallboy full suspension 29er... yes, with a Lefty fork on it...
Here is some RAW video with some good views and some techy rock crawling:
