Windshield replacement
 

Well, the crack in my windshield finally grew from the 6 inches it held steady at for months to about 18 inches, all in today's hot weather. I've been shopping around for windshields and I realized I really know nothing. The dealerships just point me to third parties. My insurance somehow doesn't cover windshields even though it's as comprehensive as they come.

The vendors I've called seem to have three options:

Basic windshield - ~$320
"OEM grade" windshield - ~$375
Nissan part-marked windshield - ~$720 (!)

Can anybody tell me what the differences really are? I don't want to get a shoddy quality windshield that is going to crack easier but I don't want to pay $720 either. Will an OEM grade part have the same dot matrix pattern around the mirror, etc? I'm thoroughly confused and the vendors can't tell me the differences; they just basically look at a part number in a computer or something.

I'd also try a Nissan junk yard.

I had mine replaced with the OEM grade replacement. No issues, and the only way you would know it's not the original is a different logo on the glass.
