The Ergotech Freedom Monitor Arm is offered by Amazon for $73.51. That is $16+ off the typical rate of $2 of the lowest Amazon price we have observed in more than one year. You may be missing if your monitor is on your desk with its inclusive stand. I chose a similar assembly some time ago and I love the ergonomics it brought to my setup. This particular mount is ready for displays weighing up to 17 pounds, which will support most monitors and VESA- iMacs. 4/5 stars ratings.
