I've been dealing with Ikelite for about 6 years now. I've always been elated with their service and advice. Please forgive me if I sould like a commercial, but my endorsement is on the level!
I've just returned from getting my new Ikelite housing for my Nikon D100 wet with a pair of Ikelite DS-125's.
I am pleased to report that EVERYTHING WORKED PERFECTLY as described. Not a problem or hiccup with any of the Ikelite product. Best of all, no leaks!
Brett Foster's suggestions were followed and the pics I shot were leaps and bounds better than the pics I had been shooting with my Coolpix 5000! Neither my wife, nor I could believe the difference a DSLR made!
(Ike suggested a few Jack Daniel's when I tried to fit the Nikon 17-35 to the Ikelite case. He was right. Jack made everything much easier. No more beer when working on an Ikelite product! 
)
If only American businesses could take a lesson from these folks in Indianaoplis. If someone were to ask me what company says what they do and does what they say, my first answer would be: Ikelite!
Ike, you've got a helluva company with a helluva a group of folks! Congratulations!
