Does anyone have Ninja Five-O?

[radioioRobert]

Hey,

I have been looking for a copy of Ninja Five-O to play on my DS. It's a Gamboy advanced cartridge, but for some reason I either can't find it, or it's over $100 when I do ($149 right now on Amazon marketplace). I've consistanly seen it listed as one of the all time best GBA games, but why is it so much?  Anyone have a copy they want to part with? And the big question, does this game live up to the hypeIs it worth the $?
