splwaterhousings.com/Couldn't edit my original post, but I bought my housing from these guys. Very happy with it and it wasn't overly expensive. Still lets you play with the aperture and exposure while in the housing which is a huge advantage.
I think these retail for around $1500, but well worth it for the amount of fun you can have with them.
I've noticed alot more people getting into surf photography lately, there were 2 guys shooting from the water last time I was at Dolls Point...
