Yeah, getting deals like that is the best. It's a way better return than the stock market and you get to play with your investment.
Video games don't bring any "real" money any more. Only the super rare dedicated ones(Major Havoc). It's seems like you can always get your money out of a pin if you really have to. Or if the profit potential is too high to ignore.
I'll always love old school games but pinball is really addictive. I barely play my videos anymore, except Baby Pac-Man(both). I play the pins every day.
