I know people are using the ColorMunki to read the 21-step ramps, but I think it uses too much paper based on the size of the sample area. The software is consumer grade and focused on color printing. It just isn't very versatile or meet the needs of creating QTR profiles.
I don't have experience with SpyderPrint spectro or software, but plan on getting one to create a profile creation workflow with it. I am sure it works just fine, but I don't know how it integrates with other software or what the format of the measurement data looks like.
I think older Mac operating systems to be invaluable for creating and comparing QTR profiles. I keep around a 10.6.8 computer/partitions just because of Rosetta and the ability to run some older software. Measure Tool, which was is bundled with Profile Maker 5, can be replaced with ColorPort on new OS, but Measure Tool is so much nicer and easier to work with when measuring strips (and targets made with excel or text editors). I have not used the newer i1 Publish Pro to know if it has the same capabilities as X-rites Profile Maker 5 or the old ColorLab software. ColorLab's mode conversions of XYZ/LAB data from i1 is extremely nice and doesn't require multi step conversion functions in excel (it can convert from spectral data as well).
