Why it's a good deal: Roku's newest streaming video player will be the cheapest of its kind available on Black Friday. It normally retails for $50.
The fine print: The Roku SE is more limited than pricier streaming gadgets. It doesn't have the latest Wi-Fi technology, voice search or 4K support. It has a remote, but it lacks some of the smart remote features of higher-end Rokus, including Bluetooth and a headphone jack.
