I recently purchased a DKC-850 for my Yamaha piano. Accordingly, I have a DKC500RW Control Unit and a DCD1 CD Player for sale. In addition, I have all the mounting brackets and manuals.
I will entertain reasonable bids for the units and sell it to the best offer. You can contact me by email or call at 760-845-8345. I live in Palm Desert, CA, so if you are interested and close to my home you can visit me to inspect the disklavier.
