Shameless plug because I work for Confused.com but give us a try!!! I would say that we pride ourselves on "price accuracy", which means the price we quote is the price you pay, as opposed to other sites that quote based on assumptions that give a cheaper price to lure you in, until you go to the actual insurer and see the "real" price.
I am insured with Elephant, for what it's worth. I pay £220.
Directline, pretty good if your car isnt modded, bit of a nightmare if it is...
Always found the `real` sites to be cheaper than any comparison websites simply because the comparison websites take commission.
Just cut out the middle man and deal with the company direct and its much cheaper.
