In this day and age can't you just get one made overseas?
Sure you could. You could burn your own cds and load roms on a flashcart too, but that doesn't mean it's the same thing.
Not to say that this thing is worth big monies (it sure as shit ain't to me), but they're trying to gouge based on perceived rarity and collectability, not because some casual joe has no other options for storing their TE.
