Buying a used pinball can be very tricky......there is a great range of qualities of machines available to purchase, and there are alot of sellers that are known to sell low quality merchandise. Before you go ahead and buy a pinball, check out the usenet group rec.games.pinball ....http://groups.google.com/group/rec.games.pinball?lnk=sg .....ask about the machine you want to buy, ask about the seller, and what to ask the seller in order to ensure that you know what you are buying. Happy pinballing!!
