There is a reason prices vary so much for 1.0" extruders used in the plastics industry.  Brand, age, and specs all play a role in the final price.  You can pick up an older Killion extruder with a DC motor for as low as $6,000 at Arlington.  We have newer American Kuhne extruders with AC motors that will set you back closer to $20,000.  $20,000 is still 50% less than a new machine. A new machine will set you back around $45,000.  Whether you are a bargain basement shopper or looking for something a little closer to new, most of our extruders have been test run prior to shipping.
