I have the same problem, due to the fact that I live over a certain distance from the "Exchange". I take my solace from the fact that I was hamstrung with BT (Bloody Terrible) for about 2 years at a combined price of £65.00 for Broadband (upto 1MB) and telephone, which included free local call after 6PM. Thanks BT.
My point being that I had to accept poor download or upload speeds but wanted better value for money, Tiscali have done this by providing a package of WIFI Broadband upto 8MB never gets to 1MB which I can live with, Free line rental, Free Telephone 24/7 to 10 international destinations, National and Local.
My average monthly cost after the initial set up cost is £27.00 a no brainer for me.
Obviously users who download DVD etc would struggle with this but for me to get rid of BT is a joy.
