Why would you sell it for less than you have invested in it? Just curious.

I have bought nearly all of my projects via Craigslist for one or two hundred bucks apiece. Seriously rough projects but that's what I like. I enjoy salvaging stuff that was given up for dead by their previous owners. Save a search for "pinball machine" on Craigslist with automatic email notifications for new results. Something will come up eventually. Be ready to pounce immediately when it does. In my neck of the woods waiting half an hour to call/email on an ad is too slow. Keep an open mind on titles. Three of my favorite machines came to me as total unknowns. I had no idea if I would like them since I had never played them and they were non-functional when I bought them. Good luck....
