Everything burningforce says is correct. I use IPS and perfer IPS over all others, ya there might be a bit delay but compared to all the other delays in your system and internet connection its minimal.

I have 5 of these: HP2335, its the same IPS panel Apple uses. You might find a deal on those on ebay but they are discontinued.

My 28 inch Hannspree is holding out well but I don't have any off axis reason to watch it.
