We went Sky after getting thouroughly cheesed of with NTL. Think of going for a higher spec package though - If you go for the top broadband package there is no installation charge and free calls all the time, including some international ones, is only £5 extra.

Rather that £28 we now pay around £35 but the service is excelent. Don't forget you do need a BT line.

Cheers
