I never noticed any banding with my Dell 22" 228, just backlight uniformity issues, blacklight bleeding at edges and naturally no real blacks, other than that I cant say it looks any worse than my 17" trinitron. Colors were never a problem for it. I am using settings that someone obtained with a spider calibrator btw.6bit panels suffer banding, granted you do get used to it and after a while you dont notice it, unless like me your running it next to a 8bit panel
ps: how about a dell 22" (they have a good reputation)
