another happy Dell U2711 owner. Great monitor for the price. the 30" is great for photo work but isn't my favorite to game on or web surf.
The NEC monitors people have mentioned (PA271W) are a little nicer (not that much) and cost a little bit more, maybe justified for some. I've never owned one but worked on them enough to know they work well enough.
The Eizo stuff is a step up from there and can be color corrected easily if you need that. The money for me just didn't line up for these monitors as a serious hobbyist. However, if I were a professional who needed this as a real everyday tool this would be the monitor to buy.
The NEC PA do have the 14bit 3D internal LUT so they can be calibrated to a perfect sRGB though and the tone response curve can also be internally calibrated for that mode and wide gamut modes so you don't give up any shades, it's all done 14bit internally.
