Apple TV (3rd generation; $69)

Yes, Apple just came out with the fourth generation of its streaming box, which adds an app store, voice search through Siri and a remote that doubles as a Wii-like motion controller for gaming. But if you don't care about those features (say, if you're not a big gamer) you can snap up its now-discounted previous model , which does most of what the new one can for $80 less.
