Colour critical photography? Eizo for my vote.
Fantastic straight out of the box, and offer not only standardised but also manual colour calibration.
The magazine I do pre-press for uses the same printer all the time. I can calibrate my 22" Eizo, then 'tweak' it to EXACTLY match their proof output. I then know that what's on my screen will perfectly match what the pressroom guys are printing to. The only way to get perfect colour soft-proofing, and ultimately the best possible final product.
I actually have it beside my 27" iMac via mini-display port, and just use it for images, and use the big screen for design, web, finders etc.
