You should indicate a budget so that we can help you in a better way.
I own the SpectraView Reference 271 and I find it a great monitor (NEC PA271W). It is nearly as big as the 30” version (301) but it has larger color gamut, better uniformity and deeper black. The resolution is also close to the 30”, so the work space is almost the same. 27” in my opinion is the way to go. I also have the 24” version that I use as second screen and it works great, I only need a bigger work space for my needs.
I am using both the NEC monitor with the basICColor Discus. This hardware gave me better shadow details than the i1Pro REVD that I recently purchased with the recent i1Profiler software. I also find the basICColor Display Profiler a very good software and I like it more than the i1Profiler. The main noticeable difference that I found using the Discus that I found is that I can get no color casts in black to white gradients and I also see more smooth gradients. Using the i1Pro because of the noise of the instrument I always got some green or red in the shadows and it wasn’t nice for me to work with BW images.
I don’t understand French but I think that the images in this video can nicely describe the Discus behavior. (see minute 1:25).
http://www.youtube.com/watch?v=A7usvCURw9sIn my opinion if you are going for a new monitor you will also need a good instrument like the Discus to use it “in the right way”. Probably the best 1200$ that I spent for color-related instruments (I also have a SpectoLino with Spectroscan, re-certificated by X-Rite a few weeks ago, 2 i1Pros, a ColorMunki, an i1Display 2 re-branded by Nec and other stuff).
I also like very much the EIZO GC245W, I spent just a few hours in front of it and I’d like to test it more closely, but I think that the idea of an automated colorimeter inside the monitor is very helpful if you don’t want to bother you too much to achieve good results. For me the CG245W has a too low resolution, “only” full HD, and the solution is called CG275W, but I never tried it.
If you will choose a 10bit panel I also recommend you to go for a Windows 7 64bit machine with a 10-bit capable graphic card. You will need a Display Port and PhotoshopCS5 64bit. At the moment the only graphic cards that seem to work correctly in 10bit mode are the ATI

I don’t think that NEC is better than Eizo and I owned monitor from both brands, I now own Nec because I love the SpectraView software and the Discus and I also got a good price with good warranty conditions.
Hope this helps!
