ntlworld.
Pros:
-----
10 quid pm that gives 24/7 access to a freephone number.
You also get 10 quid worth of phone calls.
Download rate slightly faster than what I was achieving with either Virgin or Freeserve
Can check phone call account via the internet. Not any different to BT but still handy.
ntl: send you an email giving ~10 days notice of the forthcoming direct debit payment they're about to transact.
Cons:
--------
The 10 quid worth of calls is at ntl: rates - roughly 1p p/min less than BT but PLUS a 3.5p connection fee.
Automatically charged for a once-only 10 quid interface box for your phone line. Arrives within a few days of registering.
Takes bloody ages for the sign up CD-ROM to arrive. Apparently ntl: are limiting the sign up rate to ensure their system can cope.
Difficult (but not impossible!) to sign up without having the CD-ROM installation routine tromp all over your perfectly satisfactory system setup.
Conclusion:
------------
I'm happy with them
