Quoted from winteriscoming:

I guess it depends how far you want to take it. It's a wonderful moment to be an AP owner since new playfield, plastics, and backglass are available. I have invested in all of these for my game, but I plan to keep it. I think you'd be hard pressed to break even on selling after a restore with repro parts, but maybe I'm not aware of a surge in value on this game since I bought it several years ago.
It looks like you've got a busted pop bumper cap, and I don't think those are available.
I'd approach it by getting everything you've currently got working and decide if it's a keeper. You may be looking at a couple hundred more dollars just getting it up and running if there are many coils to replace along with whatever components needed for board repair, more if you end up replacing rather than repairing a board.
Repairing boards on your own is cheapest, but you'll need to be able to desolder, solder, use a multi-meter, read schematics, and otherwise be patient with troubleshooting to track down problems. I've spent many hours working through board issues in my games. It does end up costing more than you'd think because you'll need one-off components here and there and tracking down a single source for a one time order is difficult. When you end up sourcing components from multiple vendors just to get everything you need, shipping costs and relatively high prices for small volume orders one add up. Even if you could come up with a definitive list of all the parts you need to replace in advance, you very likely would not find them all from a single source. I enjoy board work, but totally understand the appeal of paying someone else to do it.
