Most of what you just said. x3 on the pinball carts. One for the basement, one for the garage, and one at my parents' house where another dozen machines reside.
My tool sets have all evolved around what I need for shopping out a pinball machine and I have three sets - one in the basement, one in the garage, and one in a tool box used for service calls.
I continue to be amazed at how often the same tools apply around the house on just general upkeep.
