i buy systems for 15 dollars or less all the time in the wild. if its in the box i will go a little higher, especially if i don't have that version. you could get them on ebay. ebay has games included usually. if you have a n64, you don't have to use that rf cord....the n64 and game cube came with a av plug which can be used on the snes. i would try hitting up pawn shops, thrift stores, yard sales and even flea markets. good luck.
