Well, my NEC has had color consistency problems on a unit, and also on the replacement unit. Perhaps Eizo has better quality control? Again, I have no experience with Eizo, and people I've talked to were quite enthusiastic about the NECs. I am having a bad experience right now.
I will say, however, that their level 2 tech support people are very knowledgable and thorough. It is not at all hard to get through to them, either. They are sending me a third unit now, one they will test more extensively. Not sure why they couldn't do this for hte second one they shipped, but at least they are doing it now.
