A question for UK members

What's the going rate for broadband access thesedays? Can you pay a fixed fee per month, or do the bastards at BT still charge fees per minute on top?

i think i'm paying aroung £20-25 a month for unmetered access at 4MB.

here's a couple of links to some current providers.
