For a much easier on the neck and cheaper solution:<p>One 26" screen in the middle, two 24" screens rotated 90 degrees left and right of it. Raise the middle screen so the top aligns with the other two and push the other two down as far as they will go.<p>edit: one of the nicest benefits of this setup that I have found to date is to have a full-height email client on one side (right for me) and a full height browser on the left screen. It especially pays off when searching for stuff, no more scrolling, all the results on one page are visible at once.
