The best adjustable height standing desk is the MultiTable ModTable.
Who needs an eletronic motor in a desk? Seriously. I use to have an electronic adjustable height desk from IKEA. It was nice, and unfortunately they don’t make them anymore, but I’d rather have the ModTable anyway. It’s not that big of a deal to adjust the height with a crank. It takes maybe 20 seconds to go from sitting to standing, or from standing to sitting.
