Apparantly, u really don't care about the price... So yeah, buy Play-Yan. It's an official Nintendo product which makes it the best. And there won't be any problems using it on a north american DS. Why would there be? The DS is region free and even if it isn't, japan and america both use NTSC. I bought a $25,- GBA Movie Player myself. A $90,- Play-Yan at lik-sang is too much for me... Well I CAN buy it but I rather spend that money on games.
