Yeah, the original Mario Kart is/has been one of the most crazy expensive SNES games for awhile now.

If you want value, I'd go with the GBA version, Super Circuit. It has all the tracks from the SNES version (Retro Cup) plus 16 new ones, plays and looks near identically (mode 7 goodness), and has one or two of the newer items introduced in the 64 version (the jump Feather has been removed though). Also, portable!

A pre-owned Gameboy Advance SP or Micro is dirt cheap. You could grab one and 15-20ish (couple bucks a pop, depending on the property) GBA games for the price of one copy of Mario Kart SNES.
