That stinks. I feel your pain. I have had three windsheilds replaced in as many years. 1,000 seems insane! I rented a tribeca last year and drove it to Salt Lake. On the way I caught a stone. Called National and they told me it would be 650 bucks. Called around in Salt Lake and the prices ranged from 200 to 275. I paid 240 and got it done at the installers house. Did a great job. The windshield included a section to met ice off the wipers when parked in the off position.

Call around and get quotes from the local windsheild replacement companies. Stay away from the ones that sound like they sub out the work. You can tell because the person on the other end has no clue about windshield replacement. Ask them how they heat the adhesive. Pros have a glue heating system built into their trucks. Do not let anyone that has not done BMW's before, do your job. Make sure you can watch them work. Its OK if they offer to come to your house. The tools needed are minimal. Make sure you get OEM or equivalent glass. This is important. Also, insist on a new surround seal (if needed). Don't let them re-use the old one. Make sure you discuss the fact that you have a rain sensing wiper system. If they know what they are doing they will be informed about this already and be able to address any concerns.

Don't worry, your car will be good as new if the installer is competent. All auto mfgrs know that the windsheild might suffer damage and need replacement. Its designed to be replaced. Hope that helps
