Check the website for the engraver's assn., FEGA. Also spend a fair amount of time looking at all the engraving you can find; preferably under magnification. There is a lot of poor work, quite a lot of decent work and some great stuff out there. Learn how to tell the difference. Meeks' book is good and will educate you.

And, yes, it's true--be prepared to appreciate an engraved gun for its own qualities, not alleged resale value. My wife and I each have an engraved 1911 (one 1/4 coverage, one full coverage) and my old work gun has my name on it. I expect they will all just stay in the family.
