Mount-It! MI-732 - Mounting kit - adjustable arm - for 2 monitors - black, silver - screen size: 13"-27" - desk-mountable

This is one of the nicest monitor stands I've used (and I've used several). Very stable and firm, I use this with touch screen monitors so it would definitely show up if it weren't stable. Able to adjust the monitors easily and re-adjust if needed. Really recommend! Make sure you allow for room in back of where your monitor will be mounted as the mounts are not insubstantial.I didn't requite a second set of hands to put this all together & mount the monitors (though there was some juggling).

This is a phenomenal stand because you can either mount it on the edge of the desk, or it has the hardware to change it and bolt it through the desk / counter which I put them on work counters. Simple to install. You do have to tighten the monitor brackets as they are not that tight when you get them unless you put smaller monitors on them, but after adjusting, I put dual 22\ monitors on these all the time and it works flawlessly. I bought 4 of these."
