Want to Buy WTB: RA-4 Roller Transport Process (Durst RCP-20 or Printo)

Hey all, I'm on the lookout for an RA-4 roller transport processor like the Durst RCP-20 or the Durst Printo. I'm in the NYC area, but I'm open to working out the logistics to obtain one from pretty much anywhere.

Just wanted to add that I would also be interested in _parts_ for a Durst printo. Specifically the chemical development modules.
