This news story says Chautauqua County, New York, has sold its old-fashioned mechanical lever voting machines to a scrap dealer for only $52.47 apiece. One would have thought that the county could have sold them for more money if it had sold them to individuals on e-Bay. Perhaps some of the other New York counties that still must sell their machines will try that. Of course, the machines are heavy, so shipping would be an added cost.
There is also the hassle factor of dealing with 81 individual buyers. The scrap dealer is listed in the article. They might be willing to sell you one.
