the spindoctor

i have to get my car inspected next month, so i want to get a new winshield right before that. is there really much of a difference where you get it from, or are they all the same? any ideas on what would be a good price? i had a rock chip for 2.5+ years that never cracked until friday when i washed before a hail damage estimate. of course they could tell it wasn't from the hail, but at least i still got $3300. it's cracked halfway across now, and gets bigger every day.
