Get a new windshield. Sometimes when they pull a used one, they chip the edges. It can crack from there. It's a risk you have to decide if you are willing to take. Personally, I just get a new one from Safelite or Accuracy. Safelite will come to you home/work also - no gas needed. You can get a quote online also.
The guys at PAP will try to squeeze you for an extra $25 for pulling the windshield, if they can get it out of you. Plus they will have you pay the $30 for the windshield itself.
