Nikon COOLPIX S30
10.1 Megapixel CCD sensor; 3x optical zoom with 29mm wide-angle; Waterproof to 10 feet; 2.7-inch LCD; 720p HD video with mono sound; 2 AA batteries
One of Nikon's cheapest cameras and a truly affordable waterproof camera, the S30 cuts a lot of corners but is a decent buy for the money. There's a tiny 10 megapixel sensor under the hood and an uncompetitive 3x zoom, yet for only $120 these are non-issues. Thankfully Nikon has included HD video, albeit at 720p. Image quality has tested to be pretty dismal in anything but bright sunlight, so plan accordingly.
