I have been with Plusnet for years. Although I do pay a little extra it's worth every penny as the service is very good. You are kept informed up to the minute as to what is going on, eg updates on maintenance, outtages etc., They have been consistent over the years and I wouldn't think of changing. All the new offers from ISPs are just a way to "hoick" in new accounts. Hope that helps.
