go to Kai Windscreen at Jalan Chan Sow Lin. Same row after Honda Showroom if you are coming from KL. Look for Cian. Cost about RM2k inclusive of the rubber linings.
Try this place Dr. Cermin near Puchong Tesco. They have a number of outlets in other locations too (http://www.dr-windscreen.com/)
About RM 1500 inclusive of installations!
The windscreen which I mentioned earlier which cost RM2k is original. Surprisingly its cheaper to install the rear windscreen compared to the front one.
