I currently own a Canon PowerShot G1. I bought it to replace another 3 Mpixel camera a while back specifically because there were housings available.
However, the new S30 and S40 have avaiable a Canon-branded housing that appears to be very similar to the one that Sea and Sea sells for the A40. A buddy of mine has that housing and I've used it on dive trips with him. No complaints so far.
Given that the street price of a new s30 or s40 plus the new housing is less than the Ikelite housing alone for the G1, which would you buy? The housing for the G1 I already have, or a new camera and housing?
