Car insurers who beat quotes

Hi,

i am getting car insurance for the first and the cheapest quote i have got online using insuresupermarket.com is from screentrade.co.uk. i'm wondering if there are any insurers who are likely to beat the quote i have from ST...reading other threads it seems some are prepared to beat if you are thinking of leaving them, but as i am not insured with anyone at the moment this doesn't apply to me. so, are there any insurers likely to beat the quote i have if i give them a ring and say it is cheaper elsewhere?
