Just wonder, how much?
I think you'd be better of asking the people at NintendoAge.
They have all the collectors there.
I got one for $50 US. It was a steal. Almost actually was (from me), because the person didn't ship it to me for 6 months. They usually run for about $300 though, from what I see.
Hmmm, interesting. $300 maybe too high, but around $130-150 plus shipping should be reasonable, isn't it?
It depends which one. The AV or RF one? The aV one in good condition could cost between 8000~10000 yen. For RF one, good question.
