OP
Thanks for all the help everyone. Some of it was over my head, which caused me to do some more reading, but was fully appreciated. I pulled the trigger on the s90 and also ordered an ikelite housing today. I could have got a really sweet deal on the g10 (for Canada anyway), but got the s90 anyway. I had taught the guy that sold it to me. What comes around goes around right? Anyway, what makes it even better is that one of my buddies has the correct ikelite WA lens sitting around that he's not using anymore. Hmmm, wonder how many cases of beer that's going to cost me...
