I would strongly suggest against trying to get anything out of Tony. It took me over 2½ years to get my frame, with him "overlooking" my first order, cancelling the second, and then on the third sending me a frame with several things that I needed to have DC fix. During that process, I think I offered up to $500 to a few people who had received one, with no takers. Not to discourage you, but I would be very surprised if you now find someone willing to sell.
With the price of quests, it would probably be cheapest to just by an entire gun, steal the board out of it, and sell it off, then to find another frame and modify it to fit. If you do go that route, I would suggest either a PMR UL frame, or a Logic USF. There's one of the latter for sale here: Cocker stuff and pneumag setup...OBO
