Well, I'll opt-out, and then see how the lowest tier pans out after the next round of upgrades is completed - going ADSL is an option, as there is a BT line available.

Their 1Mbit / 30 GB monthly limit package is the same £17.99 a month as NTL's anaemic offering, and includes some TV channels and "watch again" features ... like VOD, whenever it actually turns up on NTL - looks promising, considering I'd be happy with 512k and a decent quota.
