Pinball is my business. I have 14 games between two locations and I do in home repairs. I have parts on hand to fix almost any Bally/WMS/Sega/Stern/DE game. I also have parts for various EM games. The only thing I don't really stock parts for is Gottlieb solid state games, but I do have a few parts for them. I have everything inventoried on a spreadsheet and I can quickly look up what I have and its price when I'm out on location or at a repair. So yes, I have a lot of parts, but I need a lot of parts. A game that is down is a game that doesn't earn me money. And when I'm out at a repair the last thing I want to do is return because I don't have a part. All that being said, it sounds like you might have as many parts as me, maybe more game specific parts. Do you really need all that stuff? 100+ new pinballs?
