Good Evening, Jchabalk,
Just keep your eyes open for almost any used enlarger being given away or offered for some ridiculously low price. Actually, all you need is the chassis. A couple of years ago, I picked up the chassis for a Beseler 45M (only $15) which I still hope to adapt as a copy stand. In this case I was lucky, since the motorized drive is still perfectly functional. If I ever get around to getting the job done, the thing should easily handle cameras up to 4 × 5. Almost any enlarger chassis can serve as the basis for a copy stand, and adaptation shouldn't be difficult even with just basis tools.
