And for the 92282838th time that is why there is a best offer option. I don't know why threads always insist on pointing out high prices on stuff without noting there is a best offer for a reason.
It's worth whatever someone is willing to pay for it and there just are no records of this thing being sold publicly much or exchanging hands lately.
Like I did with Campus Challenge and the Stadium Events box and manual, people said "it's not worth that much" but I sure liked it when I got 5 figures plus for each one of them, so to each his own.
