NTL Broadband gets a thumbs up from the BBC! BBC NEWS | Technology | Paying the price for cheap broadband:

I pay £25 a month for my ntl cable modem connection and it is worth it, partly because I can sit there streaming music - in my case Radio 3 - all day while downloading massive files and chatting to my friends.

Selling broadband and then saying but you cannot use it all the time and you cannot do stuff that actually uses the bandwidth is like selling a swimming pool but refusing to fill it with water because it might leak.
