I'm currently wasting £12.50/month for my anytime dialup with these plonkers, any suggestions for a replacement?
Have a look at
http://www.adslguide.org.uk for ISP comparisons. BT are offering £14.99/month for the first 6 months, free wireless router included. Most decent ISPs (I don't include Tiscali) charge around the £18-£20/month for a realistic package. Check Nildram, Eclipse for starters.
One thing that concerns me - I have a .co.uk which I don't want to lose, especially the mail address that goes with it. Would that be a problem to move to a new ISP?
No.
