As the old adage goes: If its too good to be true it more than likely is.
I've found that old adage rarely applies to arcade machines.
Typically with arcades the bigger the machine the cheaper they sell because no one has the space. Last fall I rented the largest Uhaul truck they offered and filled it with machines for a grand total of $600. all of them worked, one needed a new monitor. mostly just needed to be cleaned up.
Star Wars Trilogy is too mediocre of a game for someone to dedicate the space to something as large as a dedicated cab. And STUN Runner doesn't have that much of a following; it's too old for 90s gamers to care and too new and too big for 80s gamers to care.
A Broken Model 3 PCB in that star wars cab is worth $100 alone, that and the force-feedback joystick, even if it's broken make it worth picking up. These machines would have been picked up and brought home already if I had the space.
