Quoted from johnwartjr:I have reconditioned originals for less than $140, and can repair most originals for $60 shipped - unless there's a big hole burnt in it, or bad corrosion problems, it's fixable. These boards are pretty stout.
Drop me a PM if interested!
John Wart is great at refurbishing these system 3-7 boards, with my last two purchased games, I shipped him the board sets and they work amazing! John is the man and charges a great price to work his magic!
