I'm with KM just now too so you'll be getting your renewal in soon I'd think. Will try Adrian Flux and A plan I think. Did a quick check on confused and with a few fibs (no mods) just to get a quote then it would seem the KM price isn't too far above what they're showing.
Maybe I should phone Churchill as he gaurantees to beat your quote. That is assuming you are John Smith of middle Englandcestershire and you're a middle manager with 2.4 kids, a wife, a mistress, a dog called rex, full NCB and nothing but a parking ticket to your name.
