I've had three guns refinished by this firm in Glenrock WY. It's within a couple hours of my residence. They've done excellent work, but as someone noted, you get what you pay for and their top tier re-blue is spendy. One of the firearms they did for me was Model 15-6 with a lot of holster wear. I was very happy with the results, but it cost as much as the gun and I understand I will never recoup that investment.
