Mounting 2nd monitor above another.

[eggcup]

Hi all, I want to get a second monitor and mount it above my primary monitor, but I can't use the wall to put a wall mount on, anyone have any bright ideas or if there is a desk mounting mechanism I can buy where it's tall enough to go above another monitor ?

Thanks in advance
