Good Flat Panels?

I’m looking to upgrade to two dual flat panels, around 20-22", and wanted to know what are good ones these days?

i need it to show color very well as I do a lot of stuff with designing and i don’t want ghosting on it (where the text looks like its showing up and then has a drop shadow type thing). i don’t know much about flat panels but from what i used to know they weren’t too great. i know they’ve probably evolved but those were my biggest beefs with them.

if you can give me links to good but cheap places to buy them at, that would be very helpful as well.

thanks in advance.
