Get a refurbished Xbox 360 Premium system for $199.99 shipped
That's a killer price on a killer console, though beware the 60-day warranty--a little short for my tastes.
These will sell out crazy-fast, so I'm going to keep it brief: Buy.com has reconditioned Xbox 360 Premium consoles on sale for $199.99--and shipping is free!
This is the non-HDMI version, but it does include the standard 20GB hard drive, wireless controller, and headset. Alas, you get only a 60-day warranty--though arguably a reconditioned Xbox will outlast a new one.
This deal is $20 sweeter than, so if you've been waiting to pull the trigger on this killer console (and media-center extender), wait no longer.
