BuyDig offers the Sony Smart 4K Ultra HD Blu-ray Disc Player for $148 with free shipping. (Several stores, including Amazon and Best Buy, charge a couple of bucks more.) That's $50 under our mention from two weeks ago and the lowest price we've seen. (It's a current low by $12.) It features dual-band WiFi, Bluetooth, 4K and 3D streaming, USB, and Dolby Atmos and DTS:X surround.
