I've been recently shopping for an SG, and I tried the bottom-of-the-line Faded SG, a mid-level SG Standard, and a Custom Shop 1962 SG Custom Authentic (CA is the old "aging" process, VOS is the new).
There is no comparison, the Custom Shop SG, with a one-piece body and rounder neck, absolutely kills the other two as far as tone and playability go. I think that with a CS Gibson you will be less likely to be disappointed, but in case you are, you can always sell it and not lose any money on it.
