CAD/Photo monitor suggestions?

[BLWNHR]

I'm in the market for two new monitors for my office. I am a draftsman, and also do some photography work. I am looking for an IPS monitor that is 1920x1080 or 1920x1200.

The monitors I have been looking at are:

Asus ML239H 23", 1920x1080 LED backlit - $219 through PCCG.

The reviews are positive, though I can't find an Adobe RGB percentage anywhere.

Dell U2311H 23", 1920x1080 - $299.

The customer feedback is positive, though some people have complained about the anti-glare coating.

Asus PA246Q 24", 1920x1200 - $655 through PCCG.

Reviews say it is exceptional, some say better than the Dell U2410.

Dell U2410 24", 1920x1200 - $679.

A very popular monitor, always reviews well, though there have been a lot of complaints about colour tints on the screen with this latest revision.

What are peoples thoughts on these screens? What screens have I missed from the list (I haven't looked for monitors for about 5 years)?

Other information:
I have a Spyder3Elite calibrator that I use on all my screens.
My office has no windows, only 2 fluro tubes overhead, so glare isn't an issue.

As for budget, as I am buying two screens it gets expensive quickly. I am prepared to spend the extra on the 24" monitors if they are really THAT much better, but with the price being around triple it has to be worth it.

I work on CAD (Tekla) too, and I would recommend a 24" monitor with 1920 x 1200, the 1080 high screens always seem a little lacking. I have a Dell U2410 at work, and a 20" Dell at home. The 24" is better for work and photography.
