Looking to purchase a new "waterproof" digital camera in the $300 range. I've spent a number of hours reviewing various online forums and comparisons. I've now narrowed that list down to three. Would very much appreciate input on the following or personal experience outside of this list. Olympus TG-2; Panasonic Lumix DMC-TS5; Pentax Optio WG-3. My initial considerations are overall durability in the saltwater environment, ease of use and still picture quality. I currently use a Contour Roam for video. Thanks in advance for the good conversation. David
