I'm going to setup a desk station with one vertical monitor on the left, and two stacked horizontal monitors on the right. Monitors are about 7kg so I'm going to need some beefy arms to hold them onto my standing desk.

What monitor arms have you had good / bad experiences with?

I've been looking at the Ergotron items but they are kinda spendy

example setup

Not my photo, but this is roughly what i'm thinking of
