Grundys Insurance, anyone use it?

I have not dealt with State Farm peraonally, but I have yet to hear one good comment about the way they handle claims. Everyone I have spoken with who has ever had a claim with State Farm has had nightmares getting claims straightened out and settling for far less than what the car is worth or the cost of repair. I would only insure with a collector car specific insurer and only under an agreed value policy.
