I've been using Royal Service Center on Quaker Lane (right off King Street) for service on mine for a few years. They don't cringe TOO hard when they see a Contour by now. It helps, though, to be very specific about what you want and how you want it done, assuming you have any opinion on it, but they're pretty receptive to learning. About as expensive as any other shop you're gonna see, but for me it's extra-convenient because I can walk there from my house in about 15 minutes or so, and the cashier station is open 24/7.
