I agree. However, my camera is just a point and shoot digital, which in itself doesn't do much for image quality so I wasn't going to spend $100 plus for a housing. I'm not making high definition wakeboard movies...yet...just havin fun for as little cash as possible.
I thought of using glass instead of acrylic, but thought it might break too easily and didn't want to bother with cutting it. I've never had much luck with cutting glass.
