I don't want to advertise for another site BUT I ran a search on amazon "camera waterproof digital" and I got some under 150 right away. I'm not sure if they're what you're looking for but maybe trying some other sites than you started with would help? I'll try to find the info for my camera it's not waterproof but I don't think it was that expensive - I got it as a gift but it's pretty simple but great pictures!
