I like the Ikelite housing. When I started buying underwater gear, I did a lot of research. Here's what I discovered...
-Pretty much any major brand housing will work to keep the gear dry. I mean, for the cost, that's what they do. So the differences come down to personal perferances.
-Ikelite, with the clear housing allows you to see if there is any problem. In fact, when I bought my first Ikelite, it leaked the first time I used it...not because of the housing but because I didn't install the O-ring properly. It was completely my fault, but if it wasn't a clear housing, I would have flooded the thing and destroyed the camera.
-I also considered being underwater and trying to remember what all those controls are for. I know my gear, but working underwater with a camera enclosed in a opaque housing just adds to the difficulty. With the Ikelite, I can see the controls more clearly.
-Ikelite's line of accessories is just great.
-I have found their customer service to be top notch. On a recent expedition, while my camera was being hoisted out of a cavern, it banged pretty hard against the cavern wall. one of the lighting mounts cracked. When I got home, one E-mail to Ikelite and a quick call and three days later the replacement bracket was in my mailbox.
Here's one of the photos I took that day
