World Wide Stereo via eBay offers the Denon 5.1-Channel 3D Network Receiver with AirPlay, model no. AVR-1713, for $339.99 with free shipping. That's the lowest total price we could find by $10. (For further comparison, we saw an open-box unit for $9 more last fall.) The receiver features 80 watts per channel into five channels, Dolby Digital, Dolby TrueHD, and DTS-HD, USB, six HDMI inputs, and more.
