Nyko has just announced wired versions of their Wing (classic controller) and Kama (nunchuk). And while the previously announced wireless versions may be more technically impressive, these models are recession-friendly.
Identical to the previously released versions (except for a wire sticking out of each), the wired Wing and Kama will each retail for $US15. That's literally half the price of Nyko's $US30 wireless versions, or $US5 less than what Nintendo's officially licensed versions cost ($US20). So buying these wired Nyko products won't save you a ton of money, but multiply the price times four controllers and it can bring down the cost of your hobby a bit.
Look for the wired Wing and Kama this January.
