I would like to buy a HERO-1 or HERO-2000

[RepRap3D]

  Not sure if this would be the place for this, but I am looking for a Heathkit Hero-1 Robot or HERO 2000 robot.  They may be so scarce now that they no longer exist, but I figured I would give it a try.
I am currently working with Arduino based 3D printers, so I figured the next Logical step would be to try my hand at robotics.
I would be willing to seriously consider any condition HERO Working or non working as possibly someday I can find parts or upgrade it if needed.

 Thanks so much
