Yeah, lots of these *very expensive *very elaborate *very niche items from theme park history are things that - if you have one, you're like "that's cool" but despite the ride's popularity, its just not worth the money that everyone sells these sorts of things for.
I honestly don't see any difference between this and a koala. They're large, expensive, don't work (or barely work) and the market for one is limited to gold medal fanboys with too many dollars and not enough sense. The park made a mint flogging these off and laughed all the way to the bank, but a private seller finding someone else with the same desire to own one is going to have a hard time finding someone willing to cough that much up....
especially when the park sold them for less than that to begin with.
