Driving History Insurance

I have a friend with a less than perfect driving record …?
I know there are insurance companies that specialize in this, any good that will not pay through the nose?
AIG Auto Try or Response.com've been looking for the cheapest around and I have come to find that these companies are cheaper. Also, your friend can take defensive driving courses, its three hours and he gets a discount on insurance, especially if there are points on the license will be removed.
