Streaming sticks are a cheap and easy way to add some smarts to basically anything that has an HDMI port. They can go as low as $20, or as high as $50 or more, depending on how many features you want and the output resolution. But you can go even cheaper if you look for deals, especially if they’re deals for some of the most non-conventional options. Walmart’s Onn sticks are a good alternative, and the most recent launch in the lineup brings a full Android TV interface to your TV starting at $15.
