I know where I can get 4 or 5 new/sealed Chrono Cross for $20 each, but most of the ended ones ended for less than $20. If anyone else wants to try their luck, let me know via PM, and I'll see what I can do about sending you a copy for cost+shipping+acouple bucks for my trouble!
EDIT: Come to think of it, if there is a Greatest Hits version of Chrono Cross, the copies I know of most definitely are that.
