I just jump into Powerline network device. I pick up a Zyxel PLA407 Homeplug AV 200 Mbps Powerline for $80 buck, $20 buck rebate at amazon.com. Powerline network been out for awhile, but now seem to be maturing. It listed as Homeplug av, which is a 200mbps standard and my model had noise filter. I read a article on smallnetbuilder.com about these devices and it seems promising. For me it works very well. I run one end to a router on the first floor and the other in a second floor bedroom with a 8 port switch connecting my computer and nas. In less then a few minute plugin the two adapter, I was watched HD online content with no problems.
