FLEXIMOUNTS F9 Full Motion Desk Mount for 10″-30″ Computer Monitor and 2 USB Cables: $57.99 (matches lowest price ever, excellent reviews)

If there’s one thing I’ve learned in my decades of computing, it’s that ergonomics really matter.  It’s likely that your current monitor stand isn’t tall enough – this solves that at a reasonable price and adds additional rotation and movement features. I own a similar system and love it.
