I am about to leave for a 3-month trip to Baja California, Mexico, and I'm looking for a camera that will suit my needs for those three months. The camera needs to be waterproof for sure. I also need a camera that (preferably) doesn't take it's own rechargeable batteries. I won't have access to any electricity for those three months and therefore can't recharge a dead battery and I don't want to buy 5 or 6 of them because I assume that would be an expensive ordeal. I've looked at the the Olympus Stylus 790SW, the Pentax Option W30, and the Sanyo Xacti VPC-E1. I like the Olympus: it's waterproof, crushproof, and seems to be built pretty well for what I'll be doing. But from what I've read, the image quality leaves much to be desired. The Pentax is okay, and I've actually looked at it myself (as opposed to the other two, which I've only looked at online), but it's only waterproof up to 10 feet and I wasn't really all that impressed with the image quality. The Sanyo looks pretty cool but that's only waterproof up to 5 feet. All of them appear to only take their own batteries. Has anybody had any experience with either of these three cameras? Or would you recommend something else? Should I stop trying to find a camera without it's own battery and just buy the extras? Any help is appreciated.
