I bought a Dumore DMD-1 http://www.deltasupplies.com/dumore.htm at a garage
sale for $5. It is obviously used, but works fine. I did a search and
found out they sell new for $260!
It only has a 1.2a motor, about the same as a dremel. What makes it worth
$260? I suppose the obvious answer is the bearings, but is there more to is
(anyone want to make me an offer? I doubt it would bring much on Ebay,
because no one would know what it was.)
