Where to find a used small knee mill?

As far as machines the main ones that fit your size are the Clausing 8520/25/30/35 and Rockwell 21-100, both around 700lbs and typically with an asking price of $1500-2500. A little bigger would be a Burke or Powermatic Millrite which runs around 1100-1200lbs. I think Enco at onetime sold a knee mill similar in size to the Millrite.
