I do not (yet) own this desk, but I've put lots of research into this in hopes of soon owning a sit-stand desk. After evaluating quite a few desks, I've all but settled on the Workfit-D. It is non-motorized; the raising and lowering is enabled by Ergotron's "Patented Constant Force™ technology". That's a fancy term for "spring powered". The height adjustment is done by squeezing the handbrake on the front right corner of the desk then lifting.

- If you'd like custom dimensions, Ergotron sells just the base. The maximum recommended dimensions are available on that product page. Note the difference in capacity; presumably the surface shipped with the Workfit-D is 23 lbs. IKEA sells many different table tops in different sizes, shapes, and colors; you could go this route if you'd like some customization.

Advantages
I initially was drawn to IKEA's Bekant motorized sit/stand desk due to the lower price, but two things dissuaded me: speed and stability. I've seen multiple reviewers report that at higher heights the Bekant is not quite as stable as you might expect. The Bekant also has a very slow height adjustment. Ergotron produced this video comparing their desk's rate of adjustment with one that is motorized. The video is a little silly but does a good job making a point.
Disadvantages
The Workfit-D does not have infinite height points. It uses locking pins to secure the desk at the height you select. I don't have information on the spacing between the pin holes but personally I would be happy with what's available based on the video reviews I've watched.
The minimum desk height is also a little high. My current static height sitting desk is roughly 28". I think I'd be comfortable with the 30.6" height, but it's a surprisingly high base for desk that has an adjustable height.
