I've got the Viewsonic and happy with it. One complaint for me is that you can't have different presets with different brightness and contrast to change quickly between. There is the newer version; 2402. pcmonitors.info will have a review of it soon and they reviewed the 2401.

I have the Viewsonic XG2401 also, it's a great monitor for the price. It's a TN model, so your best bet is for this one.
