Using NTL broadband. £25 setp up then 24.99 a month thereafter. I have actually subscribed to a deal including Telephone line, Broadband (512 Kps but they have 1M and 2megs available) and 90 TV channels for £52 a month.
On the tech support side, no problem for me. Somehow when I first got connected, the connection was really slow but I called them up and an hour later (the time the agent asked me to shut down the computer for) all was sorted.
I love broadband, dial up never again !!!
