There are literally thousands of discount Xbox 360 consoles floating around online at the moment. The reason is because the newer version, the XBOX 360 Kinect Bundle has taken over in sales. If you would rather pick up the original Xbox 360, without all the novelty accessories, you should pick one up online. For some reason the Xbox 360 still retails for far more than it's worth in video game stores all across the USA.
However, you can get your hands on a cheap XBOX 360 for almost half the price you would pay in Dixons, HMV or Best Buy.
The Xbox 360 comes in a multitude of different packages but all play the same games. Most people don't or will ever need massive hard drives or HDMI support. Get your XBox 360 only with the features you need.
Please note that this is the original Xbox 360 console. If you're looking for an Xbox with a few more bells and whistles, we all have the latest Xbox 360 Elite, which comes with a HDMI output and a 120GB hard drive.
