I recently bought a PRS Silver Sky and had it shipped from Olympia, WA to ON. (Couldn't find a black one anywhere else.) A great neck on this guitar but with lots of fret buzz up and down the neck, though not with open strings. The guitar is set up to PRS spec, which is give or take .008 relief, 2.5/32 at twelfth fret low E. The neck looks totally straight. Others who have one say there's little buzz at factory spec. I have a medium kind of touch. Perhaps, just ignore factory spec....
