The U2211H (21.5" version of the 2311) is only $199 right now on Dell's Ebay store. Brand new units, and if you don't care about the physical screen size necessarily, then the $80 off may make a better deal.
What's with people and not liking a 22" 1080 monitor? smaller = better DPI.
I see you'll probably ignore this post though too, since you have your mind set on the 23"...
