I'm sick of Wi-Fi not reaching certain parts of my house, and I want to network devices that don't have wireless on board. So I'm going to roll out powerline Ethernet. But what's the best type?

I mean, there's DS2's version - supported by Netgear and D-Link - and the HomePlug AV version - supported by Devolo (good write-ups in Reg Hardware), Linksys and others.

Anyone here have experience of both of these? They're incompatible, so I'd like to be sure if I want to extend my powerline LAN in future, I'm still going to be able to.
