Your missing the point sexy. I already had sky+ but decided to upgrade to HD - which is the business i must say. So I had a spare + box which i gave to a family member who already had sky. All that was needed was the cabling running. It would actually be cheaper to contact sky and upgrade for the 30 or 50 pounds they now charge rather than pay the 80 pounds i was looking at.
Another very satisfied customer, LCD tv's attached to walls and to main aerial in loft including maghic eye for Sky access. Very professional and tidy job, very happy indeed !
