I've been using an Eizo CG21 for a number of years now, and it's great.
Given that, my next monitor will be an NEC. I was gonna get the 2690, but will now wait for the new NEC 30 inch (3090) to come out. It's supposed to be pretty impressive. I've spoken to a number of dealers and they say, once calibrated, the NEC are just as good as the Eizo, but at a considerable price break.
