Don't know if this has been posted up here yet but thought I'd share regardless.
I have a nice setup in the Man Cave here but unfortunatley when I bought my home recently there was no way to get a Network Cable over to my PS3 easily. I just went out and purchased [a powerline network adapter]
Took about 2 mins to do and it works amazingly well. Ran a bunch of 1080p's with lots of action scenes and not one hiccup.
Again not sure if this already has been posted but wanted to share regardless.
