My reasons for using ntl:
1. At the time of having ntl installed, the terms of the lease where I live forbade the addition of any satellite dishes so that ruled sky out.
The freeview site said I would need an aerial upgrade, the aerial I use is a communal one so that is out of the question unless the occupiers of the flats around me agree to have the aerial replaced.
2. The phone line, I would have switched back to BT, but buggered up the master socket when pulling out the wires to remove an extension from the bedroom and I know that BT would charge £50 or more to rectify my destroy it yourself job.
3. Broadband, my master socket had been upgraded to ADSL but because of reason 2, has prevented my return to ADSL at this time.
