In my experience, a lot of "small scale" industrial equipment such
as smallish laser cutters appears from failed or ended businesses,
and can be picked up at auction (eBay or otherwise) for a relatively
small fraction of original price.  But such equipment frequently has
built-in assumptions about things like power (3 phase, 440V, etc),
air, cooling, and "access" (YOU try moving a ton of lathe into a
building without concrete up to an existing loading dock!)
