Underwater camera for Hawaii

I'm going to Hawaii in the summer and plan on doing some snorkeling. I would like to get some great underwater shots. Anyone have any recommendations for a good underwater camera? I don't want to spend more than $100.

I was thinking about this one, but am open to suggestions.

Also if anyone knows of some great photo ops in Hawaii, I would love suggestions.

Thanks!
