I was just poking around and Circuitcity.com has the Psyclone Component cables for sale... $60 so they're a bit steep but probably the best quality cables you can get for the console.
They even had them for pickup at my local store.
$60 is too much for me, I'll wait until I can buy a $30 set at a store down the street

I bought the React ones for $25 at best Buy and they a great. The even have more shielding than the Nintendo ones.
