Just a thought guys i have a little "Hero GoPro" camera designed for remote control car racing to mount right on the car, the nice thing is its a digital camera that does a great job of video and has the same mounts as the other cam here and the housing for the camera makes it BB-proof and it is submersible to 200' (yes feet) so you can see it is nice and small, it fits nice on a small cruiser and has a 170degree front view and is clear, with a little rain-x on the housing even splashes just roll off and the view stays nice and clear, even picks up boat firing sounds etc. check it out, (and for the Canadians yes there is a on-line store in Canada that carries it in BC,
its about $150 Canadian or less. http://www.rcwings.com/store/ (thats about $100 or less for our friends south of the border) otherwise check your local hobby
shops that sell remote control cars.)

as you can see its very small even in a housing and runs on a SD card and 2xAAA batteries, great for attaching to the kids bike helmets also (tried that, lots of fun). I just put about 3 #64 rubber bands around my boat hull and cross them over the base to quickly mount the camera (one would be enough but for safety i use 3).
