In my experience, Williams game documentation is far superior to Gottlieb's so you’re going to run into the same problem switching manufacturers on any game.

That said, the Gottlieb parts availability is great and the schematics can be used fairly easily to track down most problems. More complex problems can usually be solved here on this forum.

I wouldn’t let that stop me from owning it. Once you get one Gottlieb under your belt and feeling good, it’ll unlock the door to many other great games.
