Syd - That message on Quidco must just have appeared, at least I'll swear it wasn't there the last time I looked! I've cancelled my Quidco enquiry. Quidco could do with updating thier Bethere description though, it describes the old Be Value package and not the new one.
EnZo - Impossible to tell exactly what speed you'll get without knowing more. Best place to ask is Be forum at
http://www.thinkbroadband.com/. Be use ADSL2+ technology therefore you should theoretically get better speeds than most standard broadband packages through a BT telephone line. Be do not have any usage caps, at least not currently.
