broadband deals?

Hi, I wondered if anyone had any tips about comparing broadband/phone line deals. I'm no longer in my BT contract, so I can change for a better deal if there is one out there, or negotiate with BT?. I've not got much patience and get a bit confused looking and comparing them all, but I guess I'll have to! I need unlimited broadband, (as that is what my lodger expects). I have freeview, but have recently seen advertised a BT 'youview' service (which has bbciplayer i think and a few other things - though I don't know if its free or not). Thanks!
