The Good Blokes via eBay offers the refurbished Netgear Push2TV WiDi Wireless Display Adapter, model no. PTV3000-100NAS, for $29.99 with free shipping. That's tied with our mention of a new model from last month as the lowest total price we've seen for this adapter. (It's also a current price low for a new model by $28.) Connect a smartphone, tablet, laptop, or other Intel WiDi wireless display-enabled unit to this device to see it on your TV. It features support for up to 1080p resolution, USB connectivity, 802.11n wireless, and one HDMI input.
