At the risk of sounding like I'm promoting my own sale (and maybe I am) I have been using an Olympus 6020 Stylus Tough camera, with the Olympus housing. I am not a great photographer, but I like to take pictures of creatures to bring back and look up in books, and sometimes to see if I can create something pretty, or to take portraits of fellow divers. As such, I don't want to be bothered with a big camera setup. Originally, I had an Olympus Dimage, which would fit in a pocket, even in its housing. I flooded it, so one of my priorities became owning a camera that wouldn't fry if it got wet. I went to the Olympus 720, which I really liked, but eventually the housing developed a leak, and the camera was too old for housings to be available for it any more. So I upgraded to the 6020. It's small, it takes very acceptable pictures, it's easy to use and to run the menus underwater, and it's a nice camera to have on boats and the like, because if somebody drips on it it doesn't die.
I'm selling it because my darned husband has gotten me hooked on a bigger, fancier camera. Drat! Anyway, I have an ad in the classified for the camera with strobe, but I would sell them separately.
