I'm conflicted on this. I've only used him once before as I do most of my setups and mods myself. I sent him my cheap Schecter 8-string with two requests: it needed a new nut (the old one had worn through), and I wanted a second output jack installed (I wasn't comfortable drilling holes myself). While I was there he showed me a couple other instruments; a Bo Diddley-square type guitar he was building and the binding looked terrible, and a super-Strat he built for himself, and the finish was remarkably bad. He did a great job cutting a new nut for my 8 (not an easy thing to do), but when he drilled the new hole for the second output jack he drilled through one of the pots that was installed. Kinda thinking I wouldn't trust him for anything cosmetic, but he did a great job on the nut, so he probably knows how to do setups really well.
I love that Schecter 8 for that reason: I use it as my test mule for electronics testing and tuning experiments. If he had ruined it, I had only spent $200 on the guitar and I could always pull the electronics out of it for something else. But it played great when I got it back, and the pot was one that I was going to replace anyway, but it still makes me nervous that he didn't think enough to ensure his drill wouldn't hit it. So dropping off this rare Sonus-8 with Aguilars and an incredible top makes me wonder if he'll pay enough attention to not wreck something else while he's working on it.
I'm a 2 or 3 hour drive from some repair guys that have Plek machines. Maybe this is the wrong way to think about it, but if they have one they've seriously invested in their craft and are looking to provide the best results possible.
