Just had my windscreen replaced by Novus through insurance with RAC. (2006 WRX) I only had to pay $100 excess and it didn't affect the no claim bonus. I had a number of small chips on it since I bought the car and they eventually cracked all the way through in one area. Windscreen is identical to the factory one. I'm not sure what the cost of a chip repair is but may be worth the $100 to get a new one if your policy is the same as mine.
