I feel your pain, my first pin was an over priced DE SW and I was also ripped off with it. The seller claimed it had undergone alot of work with over $900 spent on doing it up. The truth was quite different. broken plastics though out, missing light globes, missing globe holders, missing playfield rubbers, flippers held together with nails (yep thats right, nails), nails jambed into connectors, R2D2 motor not working, Deathstar target motor not working, burnt our DMD, broken and cut wires all over the place and numerous other issues. So your not alone. Live and learn, it'll never happen to me again and I bet it will never happen to you again either.
Good luck with it all and I hope it all works out well for you.
