Whats the best underwater camera?

I'm not talkin about disposals or the high tech ones they use for movies and stuff. Just a nice waterproff digital camera that has no bulky case.

Casio Optio W10. I don't own it, but if I buy an underwater camera I'll buy this one. Besides being waterproof, it has a cool time lapse mode that I'd love to play with. It's a couple years old, so you should be able to get a good price.

I suggest a web search. Makes more sense for you to check prices and features than to rely on someone else.
