the littman's are really nice.
check out dean's work. he's had quite a few people who considered littman cameras end up turning to him. he does really nice work.
I've been talking with him over the last few months about getting a camera built.
http://homepages.ihug.com.au/~razzle/littmans start IIRC at about 5-6k. Dean will build you ALMOST the exact thing, maybe not alligator skin coverings, with gold plated knobs, but a fully functional, tremendous camera that is just as accurate as the littman.
he has options on his website about what he can do, you supply a lens, or he includes the ysarex 127 that came standard with the cameras.
close focusing can be a pain with these guys though. but color neg films handle overexposure fine though, so say open up a stop or 1/2.
