I'm looking for a 2nd Display to use with my mac pro when I get it in Jan/Feb. My main display is a 23" ACD but I need another one for basic stuff like email/web development previewing, etc. I am looking at the following but can't decide between them. Can anyone give some advice? 1. Hyundai N240Wd 2. Dell S2309W 3. Samsung SM-2343BW Which one would you go for or can you suggest something else in the same price range?
