I got my STTNG in trade straight up for a Shadow I got for $2600 and had about $350 in to it with Aurich graphics and LEDs. Nice example STTNG that only needed some connectors repinned due to battery damage. The previous owner replaced the CPU and Driver board and a bunch of other stuff trying to diagnose it. I recently tossed a PinSound in it and new flipper fidelity speakers. It is for sure one of my favorite games. I have about $3800 in to mine at this point and am very happy with it. If I were to sell it I would probably ask $4500 knowing that everyone wants to negotiate. I however have no plan to sell it.
