forget off. How much did you pay for those anyway? I almost bought the all-in-one arcade box full size from Costco once. That machine was great...
I was very lucky to get them, actually. I got them for free.
My soon-to-be stepfather owned schools that had these arcade machines in storage, and before he sold the schools off, he took them out (after not being used for a very long time, there was dust all over them and paint chipping off, probably not used for 10 or so years) and gave them to me, knowing I'm into games.
There was a fourth one I was supposed to get (Asteroids), but it ended up being the only non-working one and nearly impossible to repair without spending an incredible amount of money.
