Badger, thanks for the advice and cool website. I punched in my postcode and it gave me a bunch of options for ADSL, cable and Satetellite broadband.
What's ADSL? I assume one travels over regular phone line, and cable is over cable TV lines like I currently have with Comcast?
My postcode only has 2 options for cable broadband (NTL and Telewest) and one for sattelite (AVC). The rest were ADSL (BT, Tiscali, Homechoice, AOL, Virgin, Wanadoo, Onetel and BT-Yahoo).
