We didn't as it was all tied in with a full renovation, our house is pretty big though, we have 50 ethernet ports, 30 audio ports, about 50 spot lights and a lot of double sockets!
Oh right...ok so my quote seems rather on the high end in that case. We only have sockets and switch with a few spot lights. I guess as part of the full rennovation you might end up saving a bit too...
Did you get multiple quotes?
