If you want the best colors and are going to spend that much, go with the
NEC 20WMGX2. The 204B is a TN-type display, which are very often inferior to other types like the NEC (S-IPS). The 214T is a PVA, but, while better, is still not as good mainly due to the fact the NEC has an automatic backlight adjuster. Here are calibration results of the NEC LCD vs. an aperture grille CRT:

Another bonus of the S-IPS panel is lower response than S-PVA and wider viewing angle than S-PVA and TN. The new S-IPS (which the NEC uses) even manages to be right up there in response time with TNs. I believe LG also has some products in the pipeline that will use the new LG.Philips LCD panel so if you want a non-widescreen display, you may wait a little while and see what turns up. I think LG actually has one (8 ms g2g) that uses this new panel right now, but I am not sure if it does or not. I don't believe the new LG displays will have the backlight adjuster though, which is a big plus for skin tones or darker colors, as you can see in the following comparison.
Here it is pitted against the 214T:

Select under Etape 3 to see different comparisons between the two displays. Also you can select Ecran under Etape 2 to see how it compares to the reference (theoretically (non-existent) perfect) display.
*The lower the bar the better (it measures difference of displayed color from expected color). The NEC manages to display all the tested colors within 1 pixel of difference in accuracy. Most LCDs can only manage 2 or 3, even some of the best ones.
