3D-120B : Solid, works, great accessories, if a bit pricey

Yes, it's rather expensive, but there are so few companies making decent multi-tier stands these days, and none with such a large range of accessories. I was a bit sceptical of the way the holders clamp onto the tubes with plastic clamps and still occasionally wonder if they're going to slip. They never have though.

Constructing it initially can be a bit tedious. I think the whole thing is designed such that, once you've set it up how you like it, you can partially disassemble it and leave the clamps and holders in place. Since I just use it at home, I have not needed to do this.

Note that this size (120B) is not quite big enough for almost all 88-key keyboards or pianos.
