If you're in a cable area, get Virgin. It's more expensive, but it's faster as well.

Be have received pretty good reviews from what I've been told, but I'm wondering if they'll drown in their own popularity before long.

I'm with BT. Always have been, and probably will be until I get my own place. They do have an Unlimited policy, however heavy users tend to get their traffic shaped. This also applies to Tiscali, and Virgin. In fact most ISPs who offer "Unlimited" use this.

Note that the Tiscali package goes up to £19.99 after 3 months.
