I do not understand "affordable". I bought my first pin in 1983 and have owned about 50. I sold all for more, or traded for equal or a better game. Home games always go down in value. Affordable is a Gottlieb System 1. Get a working one for less than a grand. They are fun games. Electromechanical games are low in price. They are very affordable, if you are good at tinkering. Pay 500 for one and keep it working and it will be worth 550 or 600 in 2 years. You made 50 or 100. Very affordable.
