I had some work done with them as well and was never given the promised quote. I had to contact Scott Sipe every few weeks to get the status (it was a very easy job, I just didn't have the tools for it).
Eventually I called the store after getting stonewalled by the smith and was told my gun had been back in for a week - nobody had called me! I told them when I dropped it off that it was my main carry piece and I wanted it back ASAP.
The work was done adequately, but the price seemed high (part should've been $20 or less, maybe 20-30 minutes to install, charged $100). I didn't appreciate being left hanging, so I'll probably look elsewhere next time.
