I would suggest, when making up fake names don't use names with the same first letter. A bit confusing to follow. I would say "Joe", selling the machine after he has made a deal with someone is slightly to blame although I don't know how long he was holding it for the buyer. I would also say it is in bad taste offering more money for a machine that a deal has been made for. That being said it's just pinball, move on to the next hunt.
