Bloodnok,
I was referring to the cost of getting someone in to run the wires through the walls, from the kitchen downstairs to upstairs.
The cables and switch is cheap, but the installation of 3 separate points isn't. Getting a plumber to come around to install a 20 cent washer will cost you $80.
I like wired too, just in this case, the data is not critical, even movies aren't streamed... it's just for 8 and 6yo to use the internet on their PCs..
