The cinematronics version of the game was the first vector. It is a huge beast of a cabinet but a fun two player game. Price will depend on condition. But a nice looking, fully working version is a $250-$400 game imho. If it is real nice it could be worth more.
The Vectorbeam version is the cooler and IMO the more sought after one because of the cab and it's arts. Not worth much if you were trying to sell it to joe-shmo on the streets, but worth alot to the right collector.
So price range? Yeah, maybe $200-$400. Lower end for non-working. But this price can be all over the place. Some people will trade their most prized games worth $1000 for one.
