Amped Wireless' PLA2 super power-line adapters are available from today
 

A few months after Amped let us peek at its Spring/Summer 2013 lineup, those products are now making their way to retail. The first of the bunch is the PLA2, a pair of power-line Ethernet adapters that are designed, as always, to push your internet where other hardware fears to tread. In addition, the units come with a pass-through socket, so you don't need to choose between sacrificing a plug and working internet. It's launching today for $99, and the PR is attached on the other side of the wall break.
