Good restorations start from a solid base (esp for a high production/ not so rare title). If the machine has suffered water damage, and you want a really nice restored example, I might suggest dumping this one at a loss, and put out a WTB for one you are happy with.
That said, if you just want a decent working example, I'm sure you can maybe itemize the work with the tech. Exactly how many lamps are bad.. exactly how bad are the flippers? Repro stuff is available for this title, so I don't see it being too costly.
