Selling them is a crapshoot. You might find someone who is looking for JUST
such a thing. And maybe not.

I once sold a radial arm saw on ebay, and put local pickup ONLY. The guy
who bought it drove 250 miles to pick it up. Go figger.

I don't think there's any "best" way to sell them. Whatever will put you in
contact with a buyer will be the "best".
