Help with monitor

[Pred]

I need to get a 20+" CRT for color correction(for our head photo guy). The four monitors I've picked are:

VIEWSONIC P220FB
NEC FE2111SB
VIEWSONIC P225FB-6
PHILIPS 202P40

I've read some reviews and the Philips seems really good, the NEC seems to be a little under par on graphic quality. What do you guys think?
