I actually find this one to be quite sturdy, even at full height it doesn't wobble. Maybe more to do with the way they have them setup at IKEA stores? As you can see on my setup I have a monitor, and 2 laptops on top of the table.
That's really reassuring to hear as that's pretty much all I can afford. I got a refurbished used desk and it wobbles but not as bad as the ones I tried at IKEA. Will give it another go! Thanks!
