MacMall offers the refurbished Denon AVR-1513 375-watt 5.1-Channel 3D-Ready Home Theater Receiver for $169.99 with free shipping. That's the lowest total price we could find for a refurb by $3, and $79 under the lowest total price we could find for a new, factory-sealed unit. It features 75 watts per channel into five channels, four 3D-ready HDMI 1.4a inputs, and one HDMI output.

A 90-day warranty applies, but it's not clear who backs it.
