There are plenty of ADSL comparison sites out there, check some out.

Everyone will tell you that their service is the best (apart from Tiscali users :-) but you'll find that Zen Internet tops out in all the tests.

Second to none on customer service (always at the end of a phoneline - local call, their techheads really know their stuff), no capping level on downloads, free (advertisement free) 1gb webspace and loads of packages for both home and business.

Never heard a bad word said about them....Definitely worth checking out.

Cheers,
