BTYahoo and BTB do have quite a good price on there 1mb lines now but not without a small catch.
As of January '05, there 512k Lines will have a 15 GB monthly cap, the 1mb line will have a 30 GB.
I'm with BTY atm as i have been for quite a few years, this caping is of no use to me so i will prolly be going elsewhere...
Plusnet have free Migrations?
Nildram was my first choice but it seems they have now been acquired by Pipex :-o
Also, if you could never get ADSL before because of range/DB reading, your luck may be in. it's set to go up to at least 75db for 512k, 1mb will change from 41db to 60db, 2mb will remain at 41db.
All this seems to be effective within the next month or two.
Happy days.
