honestly it is worth only what someone is willing to pay. you may get 1k for it or you may have to just about pay someone to take it. it all boils down to who is looking for one in your area. keep in mind that most folks are going to go buy a brand new $1-2000.00 machine thinking they got something better than a 42 year old machine. and for MOST of them the newer machiens are better since they can't maintain an old one.
