Millenium KS-2000

It is sturdy, stable, and can hold perfectly a Studiologic SL990 of 20 kg. The height is just fine, in the minimum position where one can block the legs with the 4 screws this way comes on 75 cm from the ground level to the keys top in my case. If you do not use those 4 screws, you can lower an additional 3 cm. Anyway lower than an actual piano, so unless your keyboard is not particularly huge [in height], you can have a comfortable hight setting.
The only issue are those screws which hold together the extension of the two lateral parts. Those are disposed "looking" downwards at almost the middle of the stand. And in my case, I repeatedly hit my kneecap in them each time I sit down to play. One solution would be to throw away one screw, and the stand is stable, because the other screw holds the distal tube. Another solution would be to throw away the above mentioned screw and get a power drill, and drill a horizontal hole through the external quadratic tube and the internal inox tube, and put a regular screwer holding everything together. Obviously who designed this stand was somebody who never played any keyboard on the prototype or was a short person, or used a higher position of the stand. A suggestion [for the designer] would be to place those 2 screws in horizontal, facing each other, and not downwards. This way it doesn't bother anyone's knee [who is tall], and also much easier to put together.

Bought this one to go with my Hammond SKX-pro. This keyboard accepts a lot of pedals: expression pedal, Lesley switch, sustain pedal, extra switch (e.g. for stepping presets). A lot of pedals underneath!

I could not use that with a keyboard stand with crossed legs. You see them a lot, they look like an X-shape.

I studied the pictures of this KS-2000 together with soms more expensive and also cheaper ones. From the picture showing details of the construction, I've chosen for this KS-2000. When it came it turned out a good choice for me: it completely meets my expectations for a good, stable and sturdy stand, which is easy to move.

I needed to adjust the stand once to match the feet under my keyboard, the height for my arms and hands and then all this is set. For moving to an other place I only have to pick up the stand, the legs are easily folded in. For setting up, just fold the legs outside and there you are. No adjustment to do.

There is only one minus: I could not find a accessory matching this stand for mounting a (small) second keyboard above it, like my 40 year old DX7. Or perhaps a vintage monosynth. But for me this is less important.

I bought it as I wanted to have a relatively good margin of safety for the amount of weight the stand can carry and the weight of my piano. A good margin will provide stability and flexibility in how I can use it. I

Stability:
I use it at home at its lower height setting, so I do not gig with it. I rarely play FFF, but FF works very well. This means that the keyboard will not wobble as you go on your FF playing : ).

Height:
There is enough padding on the top so it will not scratch the piano as you place it there. The lowest height is low enough. Sadly there is a handle in the middle of the stand which gets in the way if you want to have the stand very low and sit deeply in (but I do not). I have not tried setting it in the tallest position.

I would recommend it to friends.
