Travel Gear blog has a nice review of the Vivitar Vivicam 6200W underwater digital camera. I am a little concerned with its highest ISO being 200.
Still, it isn’t that expensive as specialty digitals go. Might also be a fun way to enjoy the beach or pool with out worrying about the elements getting to your expensive digital.
You can pick it up from Amazon. Vivitar 6.0MP All Weather/Underwater Digital Camera – 6200W
