Best Monitors For Photo Retouching?

Please help!

I need to select a monitor for photo retouching. I'm a seasoned photographer stuck with a subpar monitor of a Macbook Pro. Not discounting Macs or trying to get into a Windows vs. Mac debate. All I want is a recommendation for a monitor with the truest possible color for my budget.

I know I don't have a lot but my budget tops out at about $250.
This means I can probably get something better but refurbished.

Please let me know your thoughts.
I've heard good things about Dell Ultrasharps.

With you budget, you are out of the game

My guess is you need to up your fees so you can spend $800 to $2,500 on a good monitor that has a wide AdobeRGB gamut.

Some Dell Ultrasharps do have such wide gamuts, but they are rather small, 21.5 inches.

One of my colleagues just bought one of the new Lenovo ThinkVision LT3053p monitors and is very happy with it
