Apart from the fact that EE will no doubt belong to BT next year so the OP will be back to square one.
If Talk Talk works then it is fine, if there is a problem, then that is where the hassle is, for ADSL they are cheap compared to others.
BT always have been expensive and I thought the whole reason they wanted restrictions lifted was to offer a better value package. they still do not do that.
OP have a look at Sky as well if you want to stick with the larger suppliers.
