This one is a great deal, but it is 27". http://www.newegg.com/Product/Product.aspx?Item=N82E16824014300
There is this one that is THE BEST bang for your buck... The only deal-breaker for me is that it is TN. I can't find it, but it was a 23" or 24" and I'm pretty sure it was Viewsonic. The specs were amazing for $200.
4ms grey to grey for a TN panel? No wonder it's so cheap. My Dell IPS clocks in at 7ms gtg.
