I saw that ad and almost jumped on it, but I didn't need another project. That's a decent price for a project Triple Action in the Seattle market, you didn't overpay. Also, it sounds like you are having fun with the challenge of bringing it back to life. There are some great local EM guys that could help in the Spring once the pinball repair parties start up again before the Northwest Pinball and Arcade Show, but it looks like you are going to get through it way before then. Tim Meighan did a great presentation on EM restoration at the show a few years ago that's worth watching:

There's a local mailing list called WPC, Washington Pinball Crazies. We definitely do repair parties at people's houses, arcade nights, and most of the local people volunteer in some way to put on the yearly show. Cheers, welcome to the hobby!
