After reading of the many problems asociated I have decided to wait. I receved the self connection kit some time ago but was reluctant to go ahead and just blindly connect, it seems as though my suspicions were well founded.
I have been getting reminders to connect the new equipment by Testra but until I hear some more positive NBN experences I won't be connecting.
I have already made enquiries with other providers who are ready and waiting to sign me up and connect me to the NBN.
From what I have read in Testra's forums it is unlikly that should I connect that my home phone and internet will continue to work.
So on that basis I will just sit back and see what happens.
Ray.
