Here I go again. Is there another 30" display for the price can beat it for color accuracy? It meets SWOP standards. Apple has them for $1389 delivered with tax refurbished. I wonder what they do to them, are they worth it? Other option is a NEC 2490wuxi, $1100. excellent monitor. Other option is a 27" Imac quad I5.. $2200. Which one will give me the best output?
