My direct experience with CMMs is limited, but I also liked the Zeiss line. We had an Eclipse DCC unit with USOFT(?), as I recall. This was a 1996 machine bought new, and outfitted with the standard Zeiss ST probe head. The reason we chose it was based on the spec accuracy of the machine: volumetric accuracy at 2 microns over the envelope, about 18 x 20 x 18. It worked well, and I found it easy to use, even as a novice. Later experience with a mid-90's B&S MicroVal Pfx and PCDMIS was much less satisfying, but I didn't ever have enough time at it to get any proficiency.
