I have a Dell U2312HM, so I could provide any feedback that you wanted. I guess it is more expensive than what you said, but you should consider getting a good monitor that last longer than a cheap one.
I like all of the monitor (but the 2 things mentioned below). IPS panels FTW, 4 usb ports, fully adjustable base...
On the bad side, it has light bleeding on the bottom-right corner, though it's only seen on full black images, so it don't really bother me. And the screen is 'half matte', my previous monitor was matte and the window did not reflect, on this you can see the light it casts, but only when the blind is fully open.
I read this review prior to buying mine, it helped a lot to make the decision:
