Kodak Playsport video camera. Shoots in HD, waterproof, $140. Not as many mounting accessories as the GoPro however. I attach mine to a mini tripod, then tuck the folded up tripod legs under a cam strap on my cooler which sits in front of me on my cataraft. I snug the strap down tight and also attach a "leash" to the camera so I won't lose it if I go upside down or it gets knocked off. I haven't found the perfect helmet mount yet....still looking. I have been very happy with the footage I've gotten with this camera so far. It's small, easy to use, and it has an LCD view screen which the GoPro doesn't.
