Here is a great deal on an inexpensive digital underwater camera. Less than $64! You can't beat it for the money. It takes video also.

I actually use this exact camera myself and have had it as deep as 90 feet without issues. The online reviews are mixed but I think for the money this camera can't be beat. Just be sure to buy rechargeable batteries.
