just some input from my side on the IO...
we have one (11106/REVB) which was DOA and has been in service at GMB/XRITE twice afterwards. to be honest i'm quite disappointed by the craftsmanship of the device (we had a non levelled arm and a non working static mat due to the flex cable to be broken). plus a ac-adaptor thet failed (received an onsite exchange part).
in the past devices like the spectroscan or the iccolor were designed more robust.
we also ha a iSis in use which is quite nice but make quite some very high pitch noise (guess this will be solved once i get beyong 50 years of age *g*) - otherwise it's fast, fast, fast - simply lacking thick stock materials plus transparent media.
our solution to all issues mentioned above - the Spectro LFP RT from Barbieri. wonderfully crafted, quite fast and capable of pretty much everything you might imagine to measure.
PLUS tech support never seen before - we had some minor issues with the transparency lamp - within an hour or so mr barbieri himself called and dispatched of a spare. we needed a very special chart - next day we had the reference files plus the target.
they were also very cooperative in arranging a try & buy offer thru their german distributor...
