Roku 3

The Roku 3 media player is dead simple to set up and features enough content to make you wonder why you ever paid for cable. Plug the puck-size box into any TV's HDMI and it allows you to stream fast, stutter-free HD content from more than 1,000 providers (some subscription-based, some free), including Netflix and Amazon. A headphone jack in the remote allows for solo viewing when everyone else is asleep. [$100; roku.com]
