Unfortunately, asking a question like that is a bit like asking "how long is a piece of string?".
You'll probably get so many differing opinions from members that you'll be more confused than ever.
So to start the ball rolling, I have a broadband and phone package with Tiscali which costs £17.99 per month and includes line rental, up to 8MB broadband and free phone calls 24/7 to 01 and 02 landlines. I average 5.5MB and I'm perfectly happy with it.
Now wait for the Tiscali-haters to jump on the bandwagon. ;-))
