Getting the cheapest price is NOT the way to go. We are talking about a KEY safety device in your car here. THe windshield is part of the strutural integrity of the roof. Installed incorrectly and you can be killed in an accident during a roll over. Make sure the place is reputable. NGA certified technicians and they follow AGRSS rules. Do a little investigating. It is not all about price and water leaks.
The place I got mine from took the window out of the car then had a auto glass place come in and install it to the junk yard. so not much to worry about there I don't think.
