I have a 1911 that I had done by Robar and I was very impressed. Quick turn around, very polite, intelligent and friendly staff if you need to call and the finish is excellent.
I got Roguard put on the frame and slide, and all the internals got NP3 coated. The thing is practically encased in protective-ness ( yeah, I made that up - what? ) and covered up the 1911 dummy scratch like it was never there.
I have some pictures on the home computer. I'll post them up later if you are interested.
