I have a 8 MBit connection with BullDog Broadband. I pay £30 for the INet connection, but also have to pay £10 for the phone line rental from BT.
Bulldog are the WORST ISP in the world IMO. dont go with them, dont even get involved with them. I am being ripped off by them, and am soon to change to either BT or SKY, maybe even look into the new Virgin Media package, although they have just lost all their SKY channels (SKY One etc...) because of a money dispute.
