I have had my doubts about power line adapters due to their slower 200Mbps maximum speeds. However, after working with a couple of sets I have changed my mind about them. I still highly recommend a surge protector with an RJ-45 connection; this will help in the event of a surge through the power lines. The HP-3000E from Air Live is a very nice kit. The setup utility is very easy to use and the adapters are a nice neutral color so they will not stand out (unless they are out in plain view).
Performance was great, even allowing for HD video to be streamed through them without stutter. The Air Live kit is more expensive than some of the other kits out and this puts it off as there is not a noticeable performance gain between the kits. There was also no QoS ability with the Air Live version of the Power Line setup utility; this is sort of a letdown as it could be helpful for managing traffic like gaming and streaming video.
