Try again. The lam alone will be that much, and the ballast a few hundred
more. Add a couple of hundred for labor and add freight. You won't find
any parts or support for an Infocus unless you get lucky and the ballast
needs some generic part. Infocus requires you to send it to them for any
repair.
