To be fair, I did get my first cabinet off Craigslist for free.
Well, to clarify, the guy was posting an ad for a free cabinet. When I got there, the cabinet was pretty much a full loss. I noticed he had another cab in much better shape (converted to Street Fighter) that had a monitor in it. I started telling him about my intentions to make a "multi cabinet" and he agreed to give me the better cabinet once he took the monitor out.
He then asked me if I wanted to see his collection (which I was a bit nervous about seeing as I didn't know this guy from a hole in the wall). Turns out, he owned the house next door and the entire basement was FULL of arcades and pins. He must have had 25-30 working cabs, crane game, and about 5-10 pins. Full bar, "cave painting" rock wall, arcade carpeting, it was awesome.
I wish I would have exchanged contact info because I never saw the guy again on Craigslist. Wonder what he's up to....lol
