Cheaper to buy a new windshield, those tools aren’t cheap. The complete setup a guy needs to remove and reset them costs a couple thousand at the low end. At that point you might as well go into business. Pretty sure I mentioned it, but there are YT videos of guys replacing urethane windshields professionally , you should watch a few so you know what you’re getting into. Realistically the expense is the labor, the glass isn’t that expensive. Plus no pits, chemicals leached in, streaks that you see the first time it rains on your junkyard windshield and you turn on the wipers etc. That would suck.
