I have a Leitz Eldia contact printer. It is nearly impossible
to make completely dust free slides. That's too bad because
it is a very nicely made piece of equipment. Even exposure
seems not to be a problem using my enlarger as the light source.

The better way is to have a macro lens and/or bellows with a
slide or film strip copying attachment. There are some all
in one slide copiers, but I suspect the lenses in them aren't
likely to be particularly good.
