Thanks for your post - and your website looks like a good starting point for me.
Regarding Sky, they had two different types of Broadband. One being the Connect that you mentioned and another cheaper one I think. I'm not to sure which way round they were, but when I took out BB with Sky, they told me that I was in a "Sky Service Area" and would therefore be as to take advantage of the cheaper package (I guess this is using their own equipment at the exchange)?
It was so long ago that I signed up with Sky, that I really can't remember if it was called Connect or not.
To be fair, if Sky hadn't 'over subscribed' their BB network and chocked it, I probably would of still been with them.
Sorry if none of the above makes sense, but I will see if I can find out which package I was on
Still waiting for the Engineer he's supposed to be here before 1pm and I've not had a phone call to say he's on his way yet, but will update once he's been.
