I’m looking to buy a new lcd monitor for image editing. I like NEC and in particular their P221W-BK-SV with SpectraView which sells for less than $600 in the US. Since it was introduced back in October 2008 I wonder if anybody knows when it will be replaced.

Are there high-quality PVA or IPS monitors from other companies that I should look at? I like to spend no more than US$600.
