It would also be nice to have occasional access, I think.

I don't do enough projects to warrant full-time access to a CNC, but
sometimes I'd like to use one for a few hours, a few days, etc, and it's
nice to know there's one I can "book". I know it complicates things, but it
could help you offset the cost of owning one.
