For other people:
DE Tommy: had an issue with a broken wire between the coin door and the first ball trough switch which caused a bunch of other issues in the switch matrix and game logic. Haven't be able to find where the break is, I did a temporary fix and will likely keep the patch as is but make it look nicer. Plays fine now. Waiting on parts to shop it out for a customer.
Captn. Fantastic: had to clean and adjust a bunch of switches and stepper units causing all sorts of weird behavior. Game works as it should now, except for adding/subtracting credits. It's what I'm working on till other parts come in. Fixing it for an operator friend.
My own collection:
Flash: Plays fine, but only two of the slave displays work. Credit/match and players 3-4 displays don't work. Haven't felt like replacing them. Drop targets and power supply was rebuilt, but need to rebuild sound card. Need to replace SCANBE connectors, but they work well enough for now (I'll occasionally have to push stuff back in).
Fire Queen: Game works fine except the score motor will run at the end of the game. Starts a new game fine and turning the game off and on stops the motor. Haven't spent a lot of time looking at it, I'm sure it's a minor issue I've yet to locate
Aztec: An inlane rollover switch isn't working right. I need to rebuild the flippers but have had some issues with stuck screws. I'll probably take a dremel to it since I need to replace most of the parts anyways. Generally plays fine so I've been lazy to fix it.
Recently finished fixing a Dolly Parton (I concur, F the drop target replacement). I took it to some tourneys and it held up mostly fine, save for some more lightbulb sockets getting loose.
Everything else playing great
