Well, I'm in Canada and I have a local shop that is very highly regarded. Because if the difference in the dollar it may even be worth the shipping charges for you They offer out of warranty service on Nikon equipment.

However, I would say that most pro repaire shops should be able to (I would think) work on the gear for you, but it would void your warranty if they are not an authorized dealer. Though if you are already out of warranty, who cares?
