I surf all the time and I'm starting to get into photography. I'd really like to be able to take some photos of the waves and my friends. I definitely can't afford the housing for the 40d which is the camera I use most of the time. I've been looking around the internet and found a housing for a canon powershot 570. It's reasonably priced and so is the camera. Would this be a waste of money? or will the camera take pretty decent pictures? The housing is $250 and the camera is $129.99.
