The ones on ebay are expensive because the sellers know that they can get that much money for them if someone wants it badly enough.
I picked mine up in an auction for about $73 USD, but that was luck. The other auction at the time finished around $150 USD.
Toy Kingdom in the philippines is selling them for roughly $70 USD, (2999.99 PP?), but they don't ship outside of the philippines.
I feel like I got a good deal, since I enjoy it and don't regret buying it, but value is based on perspective.
Is it worth the money to you?
