[s-cars] Windshield Replacement Glass Brand?

[Calvin Craig]

After 16 years the glass in my '91 S4 has decided to crack.  I have been
offered 4 different replacement options:
1. Sekurit - OEM - I am not sure this is the same price as the others
2. PPG - I have seen some good reviews
3. Pilkington - I have heard more negative than good, but am still
open-minded
4. Safelite - ???

Any info. on experience with these different brands as far as durability
after install would be appreciated.  Since I got 16 years in Denver out of
my first one I am a bit spoiled :)  Also, if anybody knows of a good shop
around Denver that would be appreciated as well.  Thanks!
