Atkins has them for less than about $1600. That's about the going price.. I have seen them as low as $1300ish, but I question what you get there.
I'm about to rebuild the one in my car - blown oil seal. That's always an option if your friend or you have any mechanical talent. They are pretty simple motors. roadRacer (on here) just rebuilt a 12A for his daughter's car.
