Get to know folks, and the sooner you do it the better. Ask around who they know that has an old beat up old pinball doing nothing but collecting dust. Then get your hands on it, cheap, haul it away. The more doors you knock on, the sooner you do it, the better. Have cash, don't be hesitant to walk from a deal or two, or three. There are loads of machines out there, many just begging to be found in dark silence. Once fondled by young and hold hands alike while being paid to entertain, your collection will grow and swell to the point where you too will flip games for three times what you paid for it last week. Its how much how fast, an old adage, which will determine your success.
