Thanks for the replies.
I right now have a 3 (almost 4) yo HP digital camera, and I know they don't make a housing specifically for that camera.
Manning--thanks for that link, only issue I would probably have is that it's only good to a depth of 5 feet.
boBQuincy and MarkBarbieri - I think I know what the Ewa bags are - was worried about the leaking too, so hadn't thought too much about that.
Since I'm ready to buy a new camera, I just figured it'd be better to buy one that has a housing that comes w/ it....doesn't mean that I'm correct though.
Thanks for the comments.
