Welcome Fawar,
Price depends on demand where you are at. A lot of people think a machine like that is worth a lot of money... All you can do is try but it is only worth what someone else will pay. We really don't do any kind of appraisals on here. We do have a thread about all the high prices and goofy weird stuff we see on Craig's List and some times Ebay.

Since stuff gets deleted you may want to start in the back sort of.
