I bought a fully working one here with a Color DMD, LED's and LED OCD board for $4300 with nice cosmetics. It was sitting for a few days on the Marketplace until I couldn't resist anymore. Glad Resistance was futile, I really like having it in my collection.

Remember this game is an opto nightmare and can be very sensitive. It seems like you have a coil locked up, possible display problems, board reset issues, trough boards ($50 if memory serves) and opto issues. (Balls are kicking out trying to stage because it needs to see them in the various stages places and if an opto is out it doesn't "see" it).

Check the head & body for scuffs, neutral zone wear is common along with the blue inserts being scratchy. Check for cracked ramps (also fairly common) they are available but not cheap ($321 + shipping)

Personally I would want to be closer to 3G with $3500 being top end and only buy the game if you can do the work.

Left ramp is busted pretty badly, can't see the right one too well. They are available but not cheap.
