For me , man I had to think about this one for a while. I've enjoyed all the pins I've bought and sold. However some I don't think I would buy again for the right price however others I would. That being said the ones I wouldn't buy again are: Aztec (1976 Williams EM) Time Zone (1972 Bally EM) and the only Solid state game I've owned that I haven't missed at all is Stern Galaxy (1980). The others had something that was cool that would could and is missed at times. But to buy new games , others got to go sometimes.
