Been looking at getting sky digital installed. What i need is 2 installations (one downstairs/one upstarirs) so that i can watch different channels independently. If i subscribe to sky world for a month (change down after) then installation will cost £1 when you order online. Then i presume extra install will cost £50 but what i do not want to do is pay £215 for the extra box. Im sure i can get a second hand box for cheaper. but will sky install this if i dont buy the box from them. Also - i must have the sony stb as it goes with the rest of my setup and it has optical. I know sky direct cant guarentee this - so who do i go to who can install for £1 and do the extra install and provide me with a sont stb. I live in london (north west) and have had so much difficulty trying to locate a dealer who can do this for me.
