Audrey, I checked with my dealer and he uses a Harmon-Kardon CDR-2 burner. While he swears by the ease of use of this unit, it only copies at a 2x-4x speed which is pretty slow. But, if speed isn't a problem, this unit plugs right into the keyboard, and will make a copy of the cd it burns. It can be found at Circuit City stores, or on the internet and will run between $400-$500. You might want to wait and see if the new kn7k comes out with a built-in cd-rw. That would solve a lot of problems.
