I decided to go cheap. Since nobody makes a waterproof case for my Canon G-5 (an oldy but a goody). I bought a sony dsc-w80 and the sony case to match. My thoughts being if it leaks I'm only out a couple hundred dollars. The Sony had pretty good reviews and it seems to take fairly good pictures, still learning (I'm not only slow but also old). Still waiting for the filter to knock out the green tint from underwater pics.
Take care, Randy
