I definitely fall into the "Fix" category as well. Been in pinball as a hobby for close to 40 years and my fondest recollections are of bringing games back from the dead. In all honesty I've probably owned 500+ machines over the years, and like another poster stated, I don't think I've ever owned one that didn't need some work done to it to make it playable, at least to my standards.
I'd also suggest separating the "Fix" category into four sub categories. Art Fix, Mechanics Fix, Electronics Fix, and Cabinetry. My pin friend and I share complementary "Fix" skills. He can do art and cabinets exceedingly well, I can do electronics and mechanics. We labor swap all the time to get games we want working to the best of our abilities. Those of you who maybe have owned or played a game I've touched know the work that goes into my games. I'm not boasting, but rather saying I enjoy the process. When the game is fully functional, playing and looking it's best, my work is done and I've moved on to the next project.
As a side note I also really enjoy taking dead electronic sample games and restoring them to full functionality again. My avatar tells the story
