Play Asia question

I've been looking to buy Korg DS-10 for the Nintendo DS and this website has the cheapest version that I've been able to find ( I think Korg DS-10 is online only). The site seems to specialize in foreign games, and before purchasing, I want to confirm that I'm getting the US version. Even though the site says "Compatible with DS, no region protection" I want to confirm I am getting the US version of the game. Can someone with experience with this site confirm this?
