I'd say $1,100 to $1,200 for Cyclone. A REALLY nice one could be higher, but I haven't seen one REALLY nice in a long time. A relative of mine has one, and it works 100%, the bg and cab is excellent. Ferris wheel and ramps and so on are all fine. But the pf has several worn areas.
I have an ES and it is a better game, IMO. Mine is not perfect, but nonetheless, I'd say in excellent condition throughout. Probably worth about $1,500, maybe more.
Just my 2 cents worth.
