Wanted: Working Risograph, Mimeograph or Printing Press, with required materials.

I'm looking for an operational risograph, mimeograph or printing press. I need the ink and templates too. They are in the order in which they are preferred.

Pickup is ideal. I'm in SoCal.

This will help people. If you can find one and let me know about it, I would be very grateful. If I get the one you have the connection to, I'll kick down some cash to you too.
