Hi all. I've just discovered that the PLE 300 product has been discontinued, which is pretty upsetting as I planned on expanding my Network to another room and when I researched for a powerline adapter, among all the woes for other products using Ethernet over mains this particular model ahd more positive reviews than most, so I took the plunge. Its been almost a year now and I am very impressed with its performance. I have it streaming Netflix video to my XBox 360 downstauirs as well as using the Boxee for my Media files. Now that I want to continue using the same product for expanding my network I cannot find the expansion adapter anywhere online, or the full kit for that matter. So..since I want to stick with Ethernet over mains which is the best solution? If cisco/Linksys refuse to continue producign the PLE 300 can I mix and match with other makes such as DLink or Belkin? I wonder if the negative reviews of Powerline adapters are due to the age of the house/power source? I live in a new house and its been working perfectly.
