Thanks both.
I called Galle Motors, still waiting for their call back after checking stocks.
I called SamWH at Panchi, they gave me the price but when I inquired about the brand, the axx hole there said its Malaysian made but didn't give me the brand and for me to lookup in the net.
I called SamWH at Kelaniya, that guy was very nice. Told me it will cost 35k (heated) with installation. Said its Nippon brand and made in Malaysia. 10 year warranty. If its actually the Nippon Sheet Glass company, then I think its a good brand.
