Saw this powerline kit with 4-port powerline switch. Amazon is selling it for almost twice as much. Even on Ebay, price is 45% more.
Here’s the link:

Make sure to go under the "New" marketplace link.
The Adapter or the Switch by itself is going for the same price.
I like to use powerline to avoid some interference issues in my house.
