Cnet: Whoa! Buy.com has the refurbished Xbox 360 Pro for $155.99 shipped. That's way less than the price of a new Xbox 360 Arcade, which has no hard drive and only a wired controller.
The Pro comes with a 20GB hard drive, a wireless controller, and...drum roll...HDMI! However, although component video cables are included, HDMI is BYO. (Meritline, always a good source, has a 6-foot HDMI cable for $4.99 shipped.)
The 360 is not only a killer gaming console, but also a damn fine media center extender (meaning it can stream music, videos, and photos from your PC).
