Windscreen Replacement

[jimbo1812]

Has anyone used one of the standard insurance companies preferred windscreen fitters. I have just had a crack appear in my Windscreen after a couple of stones being thrown from up lorries on the way to work that other day. Are they any good ?. i have just contacted my insurance company and the say that i have to use them, if they are unable to replace it, they will look at a specialist to replace it. Do i forget it and go straight to the specialist and take the hit for the windscreen.
