Very easy to get new, I don't know what people you know, but do know that some people will fit the screen and "accidentally" write the wrong details down from another insurance/car, they really should be more careful!!
When I enquired late last year it was £130 cash fitted, and the co I use can normally kill all the excess, though due to glass limit on my policy I did have to pay £10 towards a tinted with top tint heated.
Only advice I can give is shop around a lot, they only need the slightest little ding in them, when taking out s/h ones to crack, but your choice.
