Well for the cheapest alternative (not buying a media center at all), if you are close enough, or don't mind running cable around your house, buy a graphics card with a TV-out can be had for as little as probably 40 dollars, most use an s-video out, but I have seen a few that have component out options, and run the cables to your tv and voila you have a computer on your tv. Just run an accompying audio cable from the computer as well and you are set, thats what I've done for years and it works well.
