glass repair?

Does anyone know what a good price would be for replacing a side door window for an 89 3.2 carrera cabriolet? Just bought the car and someone chucked a rock through the window last night... thankfully I didn't have anything of value in the car. I guess that's life when you choose to live in a city and don't have a garage. I'm trying to figure out whether or not it would be worth it to get it done through the insurance company or just pay for it myself.

It is about 2 hours of labor to replace it, but I am not sure about what the glass will cost.

Thanks for the response. That sounds like it could get expensive if i get it done with a porsche mechanic/shop. Do you think that any auto-glass place would do a good job, or should I go to a porsche place?

It isn't exactly rocket science, I would imagine a good glass shop could do it.
