I recently broke one of mine. The housing broke, but the mirrors were intact & hanging from their heating wires. Tapped it up until I got home & then went to work with some epoxy & fiberglas. sanded & painted & it was like new. The glass part is inexpensive, but that housing is a lot of money (around $200 I think)cause it comes with the motor section in it.
