Hi guys,
Great thoughts so far, keep the tips coming.
As for the background if and when I sold it - I would definitely include the build details along with some photos to show the work - I don't agree with hiding that sort of major thing and I'm not doing it for the resale though I don't believe it would have the same value as a original restore. It's more for a challenge and achievement.
When you see a restored Kiss getting $5K or more I think it is a feasible project to rebirth a pinball and once finished something to be proud of considering I got the Harlem for $1K and the cabinet is solid.
I will keep thinking for the moment and if I go ahead I will start a new story showing the joys and challenges of the project.
If you have the time and resources, I'd do it. There is no harm in trying and there's plenty of help on the forum. I think the only "real" issue would be the "Aux lamp module" - not sourcing one, but creating a wire harness. I would still go ahead with the project.
