Andrew, I wonder if you can/would comment on Lacie 324i monitors. They are more expensive than the NEC but I wonder if they warrant the extra expense.
Last year I worked with a fellow with a wide gamut RGB LED LaCie but I'm not certain the model off hand (I can ask). What I can tell you was I wasn't at all impressed with the software driving it. We had some issues and I called tech support on site and while the people were quite nice, their support wasn't that effective. And LaCie doesn't make anything, the OEM from others. I'm not sure why this would cost more than an NEC unless indeed it's this tricolor LED unit. NEC a very long time ago (in computer years) built an RGB LED display which at the time cost $5000! It was really nice albeit small. Very difficult engineering to do right. NEC must have learned a few things and decided not to move forward with more RGB LED displays. A review is here if for historical purposes you want to know more about it:http://www.ppmag.com/reviews/200602_neclcddisplay.pdf
Many years ago, I was a fan of LaCie and had a number of their products but the quality seemed to suffer more and more until I just moved away from keeping any eye on what they are producing.
