good guitar repair shop in Eastern Massachusetts?

Anybody know a good guitar repair shop in Eastern Massachusetts with reasonable rates?

The action on my ovation is way too high and it is taking away from the enjoyment I get from playing. I need to have it adjusted and don't want to fool with it myself because I think I'll mess up the pickup that's under the bridge. The relief might need adjusting too and I definitely don't want to mess with the truss rod.
