I've been very lucky too. I've sold and bought about 10 machines now and everything has went smooth and I've really enjoyed everyone I've dealt with. The only time it got weird was when I told a guy I'd sell him a machine then changed my mind because I was new to the hobby and thought I might be getting screwed. He was upset obviously when we hung up. I called him back 30 min later, told him sorry, and brought it to his house. Walked in to his house that night and he had 15 of the nicest machines I'd ever seen. Still talk to him today and he's very wise in the pinball world. If I cant figure out a problem he has always helped me. It pays to stick to your word. Karma if you will.
