To the OP, I have been using Mark Hama for repair work. Not nikon related (yet) but when I can't find anyone to work on a particular model, he (Mark) always takes on the job. For example, he repaired my Minolta XK when no one else would (even some that looked at it, said it couldn't be repaired). He has an xd-11 of mine now. I wouldn't hesitate to recommend him. He appears to work on most all makes of slr's as well at tlr's (he has repaired yashicamats for me in the past). Prices are reasonable, 6 month warranty of work.
