If I really though that having a coloured controller was worth a bit of extra money, and if I lived in America, I wouldn't buy that garish looking thing, it's hideous.
I'd buy a new controller from that ColorWare [http://www.colorwarepc.com/p-104-xbox360-controller.aspx] place which was reported in the News Room a couple of weeks ago.
It may be a little bit more expensive, but at least you have about 35 different solid or metallic paints to choose from, plus you can get your old controllers painted for $30.
Not that I actually do care about the colour of my controller, but if I did, I'd get a metallic Mystique coloured one, or possible Prowler, but certainly not that horrible black and red travesty.
