There are many models of the XBox 360 on the market in modern times. Here is a comparison chart of the options with the features offered in each one, and the average price found on Amazon. All 360 units have an ethernet port that you can connect to a network connection in your house - none have built in wireless. I do have instructions on this site on how to connect your unit to a wireless router.

NOTE: The "original" XBox 360 did NOT come with an HDMI port on it. It came with a basic (composite, yellow) video cable and you could buy a component (red-green-blue) upgrade cable. However, the "new" XBox 360 comes with a HDMI port so you can get true HDMI output.
