Bart,
Most insurance companies will pay to have your windshield repaired. When a huge rock hit my windshield, I called to put in a claim and my insurance company kept asking me if it was repairable because they would pay for it. It wasn't, so I had to shell out the big bucks to have the windshield replaced. The cost of the replacement was just below my deductable so it was all on me.
I've had windshields repaired before, and in most cases you can't tell where the cracks where.
Good luck.
