Gee, I did not realize that they may have stopped making the unit for the 30 since it is a few years old.

I used to use Ikelite housings, but when I was forced to get a new camera, I bought a more professional grade aluminum housing. I was forced to get a new camera because my Ikelite housing cracked around the hinge rivets. You couldn't see the cracks (under the rivet head) and the leak was slow enough that you wouldn't notice it until you were quite deep and well into the dive. That ruined my Canon. The other problem with the polycarbonate housing is that they creak during pressure changes. You'll get all kinds of pops, snaps, and creaks that will mess up your video audio. I have noticed that the aluminum housing transfers less audio, but it never creaks. While some may think audio under water isn't important, just wait till you're shooting dolphins, whales, or other noisy fish and you'll appreciate a good audio track.

still not nearly as suported as photoshop and elements, which are in use by a vast majority of photographers. what the inventors of gimp did is take the programing to photoshop and change it just enough to avoid copyright infringement and released it like the criminal parasites they are. peoples hard work and companies resource investment should be rewardeed and not ripped off by a bunch of egotistical anarchists that make up the hacker community. if you shop carefully you can find pse 10 versions for about 50 bucks. if you don't mind an earlier version on amazon or ebay you can get used copies dirt cheap. like any hobby photography has certain costs. the nice thing about digital is it eliminated a constant cost in film and developement and replaced it with a fixed cost of software.
