When you watch places like eBay and Craig's List, don't just look at the asking prices, those are usually way off base.
Follow the CL listing, see if the machine sticks around for a long time. Usually does when the prices are too high for the machine / area.
On eBay, check the ended auctions to see what similar machines actually went for.
Or, learn to use it and enjoy it. You do know this new fangled thing called electricity is just a passing fad don't you?
