wagga, I've used my Panasonic Lumix DMC-TS4 for several years now and it's held up great. I've dropped and banged it on Sierra granite and the corners are bare metal and it's still chugging along. This past week, I dropped it in the Tuolomne River without any ill effect. I don't know how long it'd stay that way with snorkeling, but thought you'd want to hear another option to research. I really like this little camera, but only wish the images were sharper. Here are three different pictures taken this past week so you can see the quality and judge for yourself.
