A DIY install of a windshield is do-able. It basically involves handling the windshield carefully (have three people available to lift and install it without breaking it), and using contractor's string to pull the inner edge of the rubber into place. I don't know about the east coast, but here in CA it is pretty cheap to have a new windshield installed (about $150 parts and labor). I recommend a pro install, if it is affordable in your area.
