This seems to be a huge breakthrough in the battle between quality/capability and price. At least with US pricing.
Eizo and NEC 27" units with near total Adobe RGB coverage seem to dominate the high end monitor market. I've chosen their lowest priced models that do this. Prices in the US, with monitor, calibration device and software (NEC Spectraview or XRite i1Display Pro) and hood:
Eizo CS270 $1,514
NEC PA272 $1,406
BenQ 2700 $ 855
Wow! Huge difference.
