at the mo i'm with aol dial up and they have offered 2 upgrad us to bb for the same price for the next yr but said cos we have a NTL phone line they cant upgrade the BB speed so will have to be just standard BB

so i was lookin at NTL BB and they do a 300kbs for about the same price as wat we're payin for aol dial up. so was wondering if NTL's any good??? or should i stay with aol.
