I stumbled upon this auction:
http://cgi.ebay.com/ws/eBayISAPI.dll...010751269&rd=1
and I was wondering if the CBS version was rarer than the Epyx version. In my experience, CBS releases go for less than standard releases but I don't really no much about it. I've never met anyone who specifically collected them. The reason I ask is that I have a particular interest in this mainly because of the unique box artwork, but I really don't want to overpay.
