take the camera to midstate camera repair on warwick ave. they will give you a free diagnosis, and if you decide to have it worked on, they are very good. they have worked on my large format shutters ( prontar press shutters) as well as my pentax 35mm bodies & lenses. i would take it to them directly and talk to them ( mark, keith or david ) ... if you bring it to one of the local shops, they will send it to midstate and charge you a commission for doing so.

they also have used nikon bodies &C that are 90 day warrantee'd, so you might get lucky and if it costs too much to repair, you can pick another one up from them, and if anything goes wrong, they are just down the street

good luck!
