economic monitor with high graphics performance

I have a samsung syncmaster from a couple years ago I love, I need another one for my graphics work. What is a good monitor to get for $150-$250 range (if that is even suffficient to get a good enough one) with good depth of black, good color, and high res.

I don't necessarily need a fast response time, its not gonna be for gaming too much and IM not sure what comprises HD, but dont necessarily need that either. My screen is semi-glossy, but I dont like the ones that are so glossy they're hard to see.

Is backlit alot better?

I randomly found these as rated high in some reviews (not so sure about the first, led one, i dont care about the energy efficiency)
