I have an iSis XL, that I use for my own custom profiles, I've hardly used it, but it just stopped working (no power up at all), and I'm surprised to see it's now a discontinued product - when did that happen? and what's the replacement now. I'll enquire about fixing, but expect it might be cost prohibitive.
X-Rite really do seem to make built in obsolescence their trademark - hardware and software. very frustrating!
