Where can I get Ikagura for the GC?

I hear there was a domestic release of it for the GameCube, however I can't find it anywhere to buy. After seeing a video of the game in action, I really would like to try it out now.

Well, you can get it at EBgames.com for $39.99 if nothing else works.

I try gogamer, bestbuy and I forget to look there. Sheesh!
