good deal on new windshield?

My wife's uncle is the GM at a Chrysler/Jeep/Dodge up in MD. I have a crack in my windshield that literally goes 3/4 across it. i don't have comprehensive insurance, so i have to replace on my own buck. Long story short, he says he can get me a OEM windshield installed for $140 (plus tax i'm sure). This seems like a good deal considering when i was talking to the traveling glass fixers (before the crack was too long....) i was getting estimates close to $100 anyways.

I am going to check around to be sure, but i heard that new glass usually cost ~$300 or so. Can you all give me your $.02?

thanks!
