Search turned up nobody via CMM.
Clean used one owner CMM's with outdated and more than likely - locked up (key) and un-supported software are cheap.
This seems like the simplest of retros going eh? (I have never personally ran a CMM.)

Getting a CMM running should be easy. And, as you say, they are around for scrap price.
As time permits, I'm making my mill into a CMM. I mounted a LASER in a tool holder and wrote scanning routines last winter. The work is published here on the zone.
Next job is to mount a renishaw probe (scored one at an auction this summer) and write probe routines.
