Mine go to Nikon in Mellville, NY. But if you go to the Nikon USA web site they list Nikon authorized service facilities and I'd have equal confidence in them. They've got a pretty short leash on them! I am an NPS member though and use Nikon in NY. I can't speak for Nikon, but they will accept your camera and give you an estimated cost if you wish. That of course slows the process, but it is useful, especially if you are worried about controlling costs. I've not used authorized service providers, but you can of course call them and see how they do things. Realize, even having your camera serviced is not a 100% insurance against problems. I "flew solo" for sometime but finally took the plunge for a second body for just this reason. I make money with my cameras and cannot afford to be without. In fact, I'll likely pick up a 3rd D700, or maybe a D800 (probably the former - I am very satisfied with my D700s.) FYI - The technical people at Nikon USA are super, IMO. They are there very long hours and can answer almost any technical question you may pose.
