I have.. I while i did not end up getting a b stock item they clearly and explicitly state and photograph the cosmetic issues rather than try to hide the issues like some other places... i originally planned to get a b-stock item then ended up with a new one (a G&L SB-2).
So, In my limited experience of the one order, they were very communicative, responded promptly (3 emails back and forth), shipped immediately and everything as as i would have expected..
As far as setup, the setup of the guitar is the factory setup.. not theirs..
I would have no hesitation in ordering from them again.. hope this helps
