Newegg offers the Linksys Powerline HomePlug Gigabit Ethernet Kit, model no. PLEK500, for $107.99. This $30 mail-in rebate cuts it to $77.99. With free shipping, that's $12 under our September mention (which didn't require rebate hassles) and it's the best price we've seen. (It's also a current low by $29.) These adapters plug into a wall power outlet to expand your home network without having to run Ethernet cables through your house and support up to 500Mbps data transfer rate. Deal ends February 3.
