Get a Wii controller and nunchuk for $35 shipped
This pair sells new for $60, but Buy.com has refurbished controllers for nearly 50% off. The warranty is a question mark, however, so steer clear if you don't like to gamble.
I didn't mind dropping $250 for the Nintendo Wii game system (well, OK, of course I did), but $60 for each additional controller and nunchuk? That, my friends, was painful. ("What do you mean you're going outside to play? Get back here and bowl with your family!")
If only Buy.com had had these deals back then: a refurbished Wii wireless controller for $22.99 shipped and a refurbished Wii nunchuk for $11.99 shipped. Grab 'em both and you're out the door for $34.98.
These are official Nintendo controllers, not third-party knock-offs. The only thing that gives me pause is the warranty: Buy.com's product pages don't indicate who covers it or for how long.
My guess, based on some quick research, is that the warranty expires after 30 days. That's pretty short, so you'll have to decide if it's worth an extra $25 to get new gear with a full one-year warranty.
Me, I'd snap these up in a heartbeat if I didn't already have four controllers. For which I paid full price. Oh, cruel fate! ("Hey, where do you think you're going, family? I paid for doubles tennis, and I'm going to play doubles tennis!")
SIDE DEAL: Newegg has Xbox 360 wireless controllers on sale for $29.99 shipped. These are new, Microsoft-branded units. It is rare to find them selling below the $39.99 list price.
