I agree with Chris. I have the 26"NEC with the tweaked eye-1 display2 and Spectraview II. I believe the monitor you chose is a close, newer cousin. SInce it has the gamut of Adobe RGB, I assume it's internally calibrated from the built-in LUTs. This is really the only type of monitor that gets close to the old CRTs for wysiwyg printing. I looked at Eizo as well but until you spend and extra grand, their monitors are similar to the NEC with similar internal calibration. The Spectraview II is insanely easy for calibration and they give you at least two quality levels. Even better for versatility is that you can make 5 or six different calibrations and then switch in a few seconds. I currently use Print Standard for all my print processing 50K, 1.8, 80 brightness, and Photo Editing which is the standard 65K 2.2 gamma and about 140 brightness. WHile the viewing is extraordinary, it is not quite as good as the old crts or the $2500 Eizo for printing. For everything else, it's excellent, and much better than a CRT.
About, the spectro. I used to make custom profiles with both an old X-rite and a newer eye-1 spectro. A couple years ago, Epson and eventually almost everyone else began to offer canned profiles which were very good, and I haven't made a profile since. I can see how with some papers and some imagery you might want to get even closer so I may get a Colormunki eventually. I can almost guarantee that you will never get a calibration of a monitor from any device which will be as good as the one you can get with the specially tuned puck and the internal hi-bit LUTs. I suggest you get the process down with your new equipment and then go for the Colormunki if you need it. Even with a custom profile you still must use ICC color management unless you own a rip like Imageprint. They have their own high bit color management which produces better color, and they provide higher end custom profiles for any paper you may want for the life of your dongle. (but it is not cheap as we both like)
