An upcoming vacation has me looking for a camera to take underwater. I don't need the latest and greatest. In my brief foray into research, it seems every camera maker makes one and that every one of them gets bad reviews for failing after going underwater. I suppose there are failures in everything and underwater cameras that fail underwater will definitely get blasted in the reviews sections. So I thought I'd ask you who own any of the "tough" category cameras for your opinions. Have you used them underwater and have they failed? I'm looking at some of the models from a few years back and most seem to still be available new in the $100-$150 range.
