I've seen MUCH better powerline deals lately from ZyXEL. The most recent (2/4/2010, but now dead) was the ZyXEL NBG318SKIT-400-SP, $40 shipped @ Newegg! That's an amazing deal considering one of the powerline adapters is also a wireless G router. Wouldnâ€™t be surprised to see this one come back soon.

Buy.com is currently offering the ZyXEL PLA400KIT for $50 AR (since 2/12/2010), except it's been constantly going in and out of stock (currently OOS). If you need more LAN ports, just throw in a $10 switch.

Heck, you can even get the ZyXEL DMA1100PKIT-SP for $60 shipped @ Newegg.

Whatâ€™s important is that ALL of these are 200mbps HomePlug AV, interoperable w/ any other HomePlug AV device (including across brands), and any other features they may possess (routing, switching, wireless, media server, etc.) are just ADD-ONs, they all functional minimally as a powerline adapter. So you can mix and match at will. It just makes sense to get as much functionality as you can, esp. if it costs less, often FAR less, than a plain ol' powerline adapter. I just canâ€™t see spending $100 or more for a pair of powerline adapters at this time. Just too many deals (mostly ZyXEL) that keep coming up again and again.
