Well, I saw the fit and build of the Sea and Sea housings for the D60/D100....I would not even consider it, but their 10D one is smaller...but who knows what the quality would be like. A friend of mine bought the D100 housing from the S&S West Coast Rep and it had apparently been "tweaked" to make sure it worked. Well, we were on a dive in Anacapa and in 2 out of 3 dives, due to a slight mis-alignment of the base tray, the housing didn't work....
You've heard from others what they said about the UK-Germany. I contacted distributor here in Canada and the guy never even got back to me....well, if he was willing to forgo a sale of that size, I wouldn't bother chasing after him.
I've used (and abused) the Subal 10D housing....and I don't consider the lack of the "*" button access a big deal....I'm used to using a half shutter press to engage AF. I'm at about 40K frames on my 10D...so I've put it to good use. Like I said earlier, 3 housings that were on the trip worked flawlessly, all the controls worked without needing "tweaking" My only gripe is that Subal needs better documentation on the housing and the housing viewfinder did rub a wear mark on my camera body....quickly fixed with a small file.
I've seen the build quality of the Nexus and Seacams and they're great, but they don't have 10D housings. If you perceive you want to shoot a DSLR now, just get it. Even if a new camera comes out....it doesn't stop the 10D...or other current DSLR from taking good pics... Moose Peterson was using this D1H's for the longest time and only gave it up for the new higher res D2h...
My 2 cents...
