I would be happy with any sys 11 because I would use the cabinet and the backbox and the generic sys 11 parts.Thinking further on this, apart from the unique Banzai Run, Swords and Taxi were the two main Williams games with microswitches for Lane Change/Status Report/HS Initial Entry attached to the flipper buttons, rather than having L/C switches on the flippers themselves, so ideally look for one of these two.
