I've got the opportunity to waste some money on something I don't really want, and I was thinking an underwater camera might be good use of this. I was thinking of something like the Olympus Tough series with a housing because it sort of seems like it might be nice to have a camera that doesn't immediately die if the housing floods. Are these cameras any good? I'm looking for something basic, having no experience and only minor interest in UW photo, but I also know that if it takes rubbish pictures I definitely won't use it. Thoughts?
