Triple Monitor Stand

[Brace]

I have been looking for a triple monitor stand that preferably hold up to 27" monitors and attaches to the bottom of my desk. Also idk if they make ones with adjustable arms but if so that would be really helpful. My budget is around 150$ and any help would be greatly appreciated.

There is a fairly popular one from Ergotech but is fairly expensive, other like theses are cheaper and usually lower quality:
