I'm currently looking into getting a multi monitor setup, and am having trouble picking out some monitors. I'm not looking for any 3D or any giant screens 21"-24" 1920X1080 are fine. I don't really know what brands to start looking at, i currently have a single BenQ G2222HDL and i love it, I would purchase 2 more, but i can't really seem to find them anywhere anymore, besides the refurbished ones that are $90 on the BenQ website. I was looking into Asus, as i have seen those have pretty good reviews, but I'm a bit confused with all the different models, i was wondering which one is their basic lineup and which one is their top of the line (I see VS, PA, ML, VE, LS, MS, VH, VK, VW under their 24 inch monitors.) 
 
So i was wondering what you guys would recommend, Should i just pick up two more refurbished BenQ G2222HDL monitors for $90, should I look into Asus monitors (if so which ones) , or look another brand?
 
Thanks for any help anyone can provide.
