For races I typically run 3 or 4 camera views. I use the HD Go Pro for the front view, and purchased the standard Go Pro's ($99 at Costco) Mount one of those stickies to the side of your helmet and try a helmet view, it's fun as well. You can have 3 views for under $500 then. Plus they all use SD cards so the media is interchangeable.
Made race review easy at WG and CMP when I got hit
