BT thus far use bandwidth throttling on my line when I try to use any bittorrent client, however in running a cost / benefit analysis between the very few providers in my area they beat everyone. So, sadly, I have signed up with them again. They have upped my connection from 512k to 3Meg and reduced the cost and increased my limit to what is called unlimited but appears to be around 100G per month looking at the contract. Only about 23 quid a month though, including free weekend calls and one of the silly broadband wireless phones on a separate number.
