The good thing about TALKTALK is you don't get any bills from BT

They also use there own equipment in the exchange, so you are not relying on BT

You get around a 30GB+ allowance in the price (Tiscali, BT, etc, all 2GB)

My mates just signed up for it, as it works out cheaper than BT & dialup. I've also heard no major complaints about it.
