Could just need some repining. I would start with the $89 rectifier board, but you have to be able to solder. Also recrimp all those connections. See what issues you still have. Rectifier should clean up a lot of the light issues. Maybe some othe recrimping of connectors. These are pretty straight forward to work on. Worst case mpu $200, solenoid $180, displays $250 or so. Great game though.

If it was closer I would say run and I would buy it.

These are very fun to work on. It's like an old car there is plenty of room to get in there and very straight forward. I say go for it.

When you go look pull the fuses and ohm them. Look for burnt connectors. Lift the playfield and look for any burnt coils or wires or light sockets that look bad. Honestly a new rectifier and some recrimping will take care of a lot if not all.
