Your best bet would be to contact AMF Products in America... but a rough estimate of the cost would probably land you at about $100,000 x amount of lanes you'll have.
Best place to contact is dependant on what you want to put in your centre. There are a number of places to contact. If you are genuinely interested please email me and ill put you in touch with the right people.
Oh and Daniel - AMF have a contact here in Australia for this (you of all people should know that )
most of the amf centres were listed for "sale and leaseback" ... meaning that they're not actually selling off the centre, just the land and building and then renting it
