Peripheral manufacturer Nyko is adding several new colors to its line of Wand controllers. Each color will be available at a specific retailer, so if you're looking for a red Wand, but have never even heard of a Fry's, try purchasing it online. The Wand colors and selected retailers are as follows:
Gamestop: Green and Orange
Meijer Supercenters: Grey
The Wands are priced at about $30. The absolutely not recommended "paint it yourself" method will run you under $20 in materials.
