I have a better suggestion, buy a new digital camera that is waterproof!
There are several brands that make waterproof cameras, but the most recent one Olympus 770SW is probably the best one available. It is waterproof to 1 hour under water. I bought it because I wanted the waterproof feature (the shockproof, crushproof, and freezeproof are also handy to have too) for my September cruise. I had previously bought a disposable camera, but it is hard to see through that wee viewfinder and the pictures don't always turn out very good.
You can also get waterproof housins for many digital cameras, but they are almost as expensive as a new camera. The one for my canon digital camera is $300!!!
