Tiger Direct at Sherway had a bunch of Kodak video cameras at $30.00. Supposed to be waterproof to 3M. No M/C mounts but for $30 one could play around. The thing I like about it over the Gopro is that the Kodak has a screen so you kow what you're recording. Runs a micro SD and recharges off a USB port. After playing with it I wondered if there was any reason a person couldn't use any junked old cell phone camera. Probably shared technology.
