I bought these a few years back and have enjoyed the new found real estate on my desk.  I have upgraded to two 27″ monitors, and this still works well. They wont sit well stacked due to the monitors hitting each other, but if you were able to find a better pole/stand, you could do it with ease.

Currently my two monitor setup is one vertical, one horizontal which suits my needs pretty well. Having both horizontal is a bit difficult due to the length of the arms.  Ergotron should offer arm extenders to allow the 27″ or larger screens, and they may in the future.
