I,m going over to Nildram for adsl, and of course BT, my NTL cable [and phone] have been great for everything except gaming, my main internet requirement.
Again i dont really care about the speeds, its the quality of line i'm more interested in. Apart from a little downtime, and hiccups after the speed increase, its been good and the help here , pretty damn good to.
It would be nice if NTL got back to the front again, i really thought cable would be the final answer against adsl, maybe it will be, but not this year.
