http://www.kustompcs.co.uk/acatalog/info_6066.html Not sure if you were aware of it's existance, but it might be worth having a look at. It's a <£700 30" IPS monitor, it's intrigued me at least
Here is the 23inch version: http://www.tftcentral.co.uk/reviews/hazro_hz30wi.htm Looks very unimpressive to me. No OSD menu, no features like side-by-side picture -in-picture, no easy adjustment, the stand looks like something I would make in 2min going at Home Depot for some construction parts. Terrible colors out of the box, and has ghosting issue. The price you will pay for such monitor + an average color calibrator, you might as well buy the Dell U2711 or the U3011, which feature factory calibrate Adobe RGB and sRGB color profile, and provides you with a full calibration report and the super expensive calibrator they used, and you are bombarded with features and better for gaming.
https://www.hazro.co.uk/duo.html is currently £1350 delivered, which is only just more than the cost of the latest Dell 30" Ive just had a windfall from the taxman.... it is seriously tempting!
