Well I ordered mine from Nintendo's store. I know there isn't much difference in Component cables. I bought it from Nintendo because I know they stand behind their product, and I try not to go 3rd party for my accesories if I can help it.
I can just imagine if I had a video problem and called Nintendo the first thing they would ask me is what type of connection are you using, and what cable. As soon as you say Mad Catz or any other company you just gave them an easy out not to help you. Companies love to pass off problems to other companies.
