I've just bought a U2410 after my old 21" CRT finally packed up and it arrived today. Worked fine, no duff pixels etc. I went for this one as it has good colour reproduction compared to cheaper TN type monitors. This is important to me for my skinning work. It also has a game mode which reduces input lag to only about one frame worse than a CRT monitor. Most LCDs with a decent image are about 2-3 frames slower than a CRT.
Initial thoughts are that the default colours are a bit too bright and oversaturated, but that can be easily toned down in the menus later. The res of 1920 by 1200 is a nice improvement in SA over my old monitors' 1600 by 1200, shame about the drop in FPS from 80 to 60 though. AH looks crisper and more detailed than on my CRT, there's more contrast between the different terrain tiles and I can pick out my tracer fire better against the sky. Overall I'm very happy with this monitor.
