Unfortunately the DS-263N is not available in the UK which is where I live. We also get ripped off on prices. We don't have much in the way of rebates over here. The cheapest I can find the 2007WFP is £253 inc delivery although he assures me it's S-IPS and that it has 0 dead/stuck pixels.
I see you have done your homework. :)
2007WFP A04 with ending L should make you clear of the panel lottery and get you an S-IPS instead of S-PVA. If you'll get the LM201W01 or the LM201WE2 which is used in the NEC, I cannot say. Dell have used both I think.
Since you are in UK, there might be an option for you to try the Hazro HZ24W:

It'll cost more, but worth looking into.
