Which waterproof rugged camera?

I'm looking for a waterproof camera for an upcoming trip to Spain. I've looked around some, and am hoping to get one for under $200. I'm no professional photographer or photo enthusiast, although I am looking for good picture quality.
So far, I'm leaning towards the Panasonic Lumix DMC-TS25, but I am also considering the cheaper Panasonic DMC-TS30. Is it worth it to go with the more expensive TS25? What are the benefits?
I have also looked into the Nikon Coolpix S32. I realize this camera is geared more towards young people, but it can go farther under water (33 feet instead of 23) and seems to offer similar features at a far lower price. If I were to choose this camera, would I be sacrificing photo quality, and if so how much?
If there are better choices for value or quality with similar features under $200, what are they and what are their advantages?
I realize i have asked many questions but I really appreciate any and all responses!
