B stock is actually better than buying used. AVS checks them out, and you STILL have the option to exchange with Sony for 60 days should some issue like banding, dust blobs, etc rise up.
Also your only posts on the forum are to sell things and you have no feedback. I think price is going to be your only friend for a successful sale here. Current used prices for this machine are in the $14k range. At least when I sold mine.
Anyway, not trying to mess up your sale, but if I were you I would just delete this thread and start over with a good price.
