I'd recommend Asus VS238H-P. I have 3 of them and let me tell you they are beastly. 2 ms (grey to grey) response time. Best part, I ordered 2 of them on Black Friday for $130 each minus $36 after rebate with no wait. I havn't had any problems with these monitors and Asus have pretty good customer support compared to Dell so I highly recommend you get Asus instead.
