Hydraulic die forming in Wisconsin

I’m looking to buy a used Bonny Doon press and would like to see one
in operation first.

I bought Susan Kingsley’s book “Hydraulic Die Forming for Jewelers
and Metalsmiths”, which was good but left me with more questions than
answers. Is there anyone in Wisconsin or Upper Michigan that would
allow me to observe the process? Does anyone have a press they are
interested in selling, or could you refer me to a used equipment
seller?
