Can anyone recommend a good monitor for editing D600 photos?

I have been very happy with my Asus Pro Art PA246Q.  It is an IPS panel with 98% Adobe RGB coverage, large color space.  Also it is 1920 x 1200 on a 24" monitor so that gives you more area than a consumer 1920 x 1080 monitor for editing.  1080 monitors are better for movies and such.  It does depend on your price range, the Eizo is probably a better monitor yet, but more cost.  The Asus Pro Art is around $500. US so it was in my price range and I have found it very good for my use.
