i have one in storage, it works and i am pretty sure it is available for the following offer.  it is well worth it should vast copies of *some awesome sudoroomian publication* need duplication.  fraction of a penny per pAge.  get in touch; i cannot personally transport it at this time (both because I haven't the truck and due to physical limitations) but AFAIK it can be set up in situ.  

for b&w copies, at least for the first rationally sized run, just add paper  (no i cannot define rationally  at the moment; but i can certainly find out).
