Was speaking to a bloke about it the other week.....he's had nothing but trouble with the system
He has had Sky back at least 3 times in the space of a month........
Depending on your house you could run an aerial cable from the back of the Sky box into your TV. You will probably need the RF box which is about £20 from Sky as the new boxes don't come with the RF output like the older boxes did
I would wait 12 months or so for the teething problems to be ironed out. Also the equipment will get cheaper too......
