Any Dell IPS monitor will be amazing. I love the Dell U2412M, it's e-IPS (6 bit) and is 16:10, one of the few 16:10s left. It's LED backlit too and has Displayport and DVI/VGA.
You can usually find deals on Slickdeals for anywhere from 230-260ish, I think.
I can attest to this. I originally purchased an Asus monitor, but the colors looked horrible. Went with the U2412M and it looked perfect as soon as I plugged it in. Awesome monitor.
