You can't trust VGPC... especially on high priced or uncommon games.
I think I looked a few months back and it was saying Mario Tennis for Virtual boy was like $34k, which I get was a glitch, but that just proves how inconsistent and unreliable it is.
On a related note, I don't follow NES games, it is the one platform I kind of try to stay away from because of the major inflation, so I don't know where cheetahmen should really be price wise, but check ebay sold listings.
