Ours has a couple of chips in it, and my nephew lightly bumped his head against one on the passenger side the other day, and it now has 3 cracks coming from it I rang our insurer, and apparently comprehensive insurance doesn't include windscreens, so the excess is $400

I thought I'd ring around for quotes today, and I've gotten 4. They range from $210 to $646! Each time they've asked me for the make and model, but only a couple have asked the year - strangely, the cheapest and the most expensive.

Obviously, I wanna do it cheap, but I also don't want it to break in a month. Any ideas on why there is such a price range?
