That said: Who the heck needs a motorized desk????? When it came to spending my own money, I got an IKEA Skarsta... essentially the same desk but with a hand crank, for half the price. Yes, you can buy two sit/stand hand-crank desks with a reliable mechanism for the cost of one motorized desk with a P.O.S. controller. Or you can do what I did, use the money saved to buy the most gigantic monitor I could find, which improves my productivity much more than the difference between a motorized versus hand crank desk mechanism.
EDIT to add:
In fact, I am pretty sure you can buy just the Skarsta hand crank mechanism. The next time I do a desk for myself, I will probably buy the leg mechanism and cut a custom-shape table top from some 3/4" cabinet ply.
