In case anyone is still looking, I just got one of these (
http://www.newegg.com/Product/Product.a ... 6824116439 ), and I can affirm that the color and contrast (after calibration and setup) is absolutely fucking amazing. I am very happy with it (this after returning 4 panels that I didn't like).
It's worth noting that any LED backlit panel under 400 bucks will have issues with blue tint and hue, which sucks, but that's the way it goes.
This includes the LG panels that prom just linked to. Don't be fooled by the picture. That's just a blank panel with an image photoshopped in.
Unfortunately, if you want to spend under so 300 - 400, I would recommend against buying an LED backlit panel. I'm sure there are some exceptions, but as someone who has just worked through 3 in the 120 - 250 dollar range, stick to LCD unless you're dropping some serious cash (but of course, to me, 250 is serious cash for a monitor).
The viewsonic I linked to at the top as been by far the best for the money, however, out of the box the colors and gamma are all fucked up but once you calibrate it, it's amazing.
Sidenote: When salespeople start talking about TN vs IPS and LED vs LCD vs OLED like they are comparing their holier than thou macbooks to your lowly win7 or linux notebook, I want to fucking choke a bitch.
