VESA mounts are only a few bucks and give you even better height and tilt adjustment. You also get desk space back. I have a shorter desk (24" vs typical 30" depth) and I have two monitors and a laptop mounted on 3 VESAs and I can extend them so that the monitor edge is inline with the desk edge, giving me the same 24" that a 30" desk would have with a monitor stand.

Which mount do you have? I've got a 24" as well and I've never imagined I'd fit 2 monitors.
