I may have the chance to pick up a used Performax 16-32 for $300...I'm going to take a look at it this afternoon. The only thing the guy has told me so far is "it is the older 'silver' model. The silver was discolored slightly in a couple areas due to a spill in someone's shop before I got it, and part of the 'feed speed' knob is broken, but still serviceable." I don't really know too much about these machines so I'm looking for guidance on what all I should look at when I go to see it. Thanks in advance.
