DSL Shootout
ADSL Guide has a comparison facility on their site that allows you to compare the performance of different ISPs. I decided to compare AOL, BT Broadband, Demon Tiscali, Wanadoo and my own ISP Freedom2Surf, you can see the results here.
The runts of the litter appeared to be AOL, Tiscali and Wanadoo. BT came about midway up the field and Demon snapped at the heels of Freedom2Surf.
