it wasn't too popular, but it might be a bit expensive there. scour ebay for a day or two if your gamestop doesn't have it cheap. gamestop's probably the easiest way, but ebay/a quick google search might net you a few more bucks to save.
Hm....... I'll go to Gamestop.com , then Ebay.com, then Amazon.com .....
Edit: I got:
$25.16+ Shipping at Gamestop;
$17.99 for biding, $19.94 for buying at Ebay;
Used starts at $17.93, new starts from $17.94, Collectible starts from $25.99 at Amazon.......
