Quoted from swillie:
Probably the authority on planet Earth as far as EM pinball repair is the one who will be fixing it, so as far as that goes it is in very very good hands.
Sounds like you have Clay lined up to get it working. If so you are in very capable hands.
Also, you don't need our help in valuing this game if Clay is around. He will be able to price it and actually owns an exceptional example of this game.
