Hmm I don't want to bother you people but I'm still undecided.
I thought I would go with the Canon housing mainly because of the shutter lever and the zoom control on the Ike but I'm having seconds thoughts now.
I read a couple more posts on this board and on other websites and I saw some quite people mentioning leaks on their S90/S95 Canon housings after a couple dives.
That can be bad luck but since I don't see too many people reporting leaks on the Ike for the S95 (actually I haven't seen any) it makes me think about going with Ike since it really seems better built (and the closing. I don't mind spending more money for the housing and having to get used to the controls as long as my camera remains safe
I'll probably end up ordering both housings and returning one after trying them out but I'd be glad to get some more thoughts on my fear.
