Harman Audio offers its factory-refurbished Harman Kardon 375-watt 5.1-Channel 3D Home Theater Receiver, model no. AVR 700, for $149.95 with free shipping. That's $15 under our April mention of a new unit and the lowest total price we've seen. (It's also $148 below the best deal we could find for a new one today.) It features 75 watts per channel into five channels, 3D pass-through, and three HDMI inputs. A 1-year Harman warranty applies.
Update: Specs corrected.
