1. I thought about buying and it was an easy fix, someone has them for 7 each.
2. Bulbs and rubbers are cheap, just time consuming. The Sterns are cool since you can turn all the lights on in the menu to track down burnt bulbs.
3.Not sure, maybe check the fuses and coils.
4.could be the switch in there. If the machine doesn't "see" the ball there it won't pop it out.
5.ball trough issues???? The opto board an the other rollover switches in the trough tell the game how many balls are installed. If you have the opto out the machine may think there isn;t the proper number of balls installed.
6. That sucks!!!!! Are there any local pin guys who keep it on hand. I know up here near Seattle there are a few guys who buy it in quantity and sell it to others. Shipping could be spendy.

I forgot if you open the coin door you can go into the menu and check all the solenoids one at a time to see if they work, that will help track down the pop bumper and hole kicker problems. Same with switch tests. Be sure to pull out the interlock otherwise the coils will not fire in the tests..
