I'm using the Ikite housing for my EOS 50E. I'm very suprised to see how may ports are available for different canon lenses. Last year I've bought a 100 mm Macro lens with a port for it. However, using the macro lens in autofocus mode was not working perfectly. Last month I was very pleased to see that Ikelite made a new port for this lens with manual mode setting. If someone is looking for reliable underwater houses which also manufactures new ports, I don't have to look further on. What I also understand from Ikelite, is that alu housing can provide some problems with condensed water (specially in cold water). The last advise I want you to consider, is if the different handlebars/knobs on Subal are maintenance free like Ikelite's are..

Jonathan, I have to disagree completely with Scuba Eric...
I have a Subal and an Ikelite housings... wow what a difference !! Starting with the price, you get what you pay for !! No joke Quality.
Machined seawater resistant aluminum alloy body, finished hard coat anodized.
The finishes are superb on the Subal, unlike the Ikelite where I had to bend some of the knobs/controls to reach and operate my camera properly !
I know you don't want the cost to be the driving factor in your decision, but still consider value to be important, so the only answer is to get a Subal.
It is custom built for the 10D ONLY and it fits like a glove, like no other housing !
It also has the most complete controls to operate the camera underwater 23 of them !
From my experience Ikelite plastic housings has provide me some problems with condensed water (specially in cold water / hot weather). It is a pain in the neck when you have to wait almost 20min. for your Ikelite housing to get rid of the condensation after you started the dive. some times it won't and you end up carrying the housing all the dive for nothing.
I still have my (older) Subal housing with less scratches then my (1 year old) Ikelite. What a difference in performance too !
Oh, and the ports available for Subal are a vast variety too. I do have similar wide angle lens too.
