The McCarty is a spectacular model. IMHO, the McCarty was a game changer for PRS. They basically changed the way they built guitars, based on advice from Ted McCarty. That seemed to be the seismic shift which finally got Gibson players' attention.
Having said that, this particular guitar looks like it's in pretty nice shape. No gotchas as far as I can see from the photos. I love the Wide-Fat necks on these guitars. If you're not crazy about the pickups, thats a very easy and inexpensive fix. (Some folks think they sound a bit muddy through some amps..) Like our forum brethren have mentioned, it's a 2002, with a non-10 Top, and moon inlays. I agree that $1000 to $1200 is about right.
Oh yeah, one last thing...I'm totally guilty of is looking for guitars with insanely figured tops. While the top on this guitar isn't spectacular, it's still really pretty. It's better than at least half of the original Gibson Flametop Les Pauls from 1958-1960. I'm sure this will sound awesome.
