I just paid $350 to a pro in Dayton, Ohio for a SS refret, new bone nut, and to swap to 50's wiring on a LP. Unbelievable results! 3:30 drive one way but it was worth it.
Originally I was looking at Glaser, Erlewine, and some others but was afraid to ship my #1. Also keep in mind that geographic location will have an effect on the price. My guy didn't charge me premium for the materials either. Showed me the invoices from StewMac and from Jescar. I paid what he paid for the parts.
