I recently helped my wife and myself install monitor arms to free up space on the table. I didn't do too much research and only decided to change it when I was window shopping in Courts.
Courts was carrying the North Bayou brand and while it doesn't look very sleek, it was quite cheap. But I went home and searched on Taobao I realised it was even cheaper (even after shipping). Paid about 60% of what Courts was charging to buy a dual monitor arm.

You have to check the maximum weight each arm can support. Most brands and the higher spec arms can support 32" monitor per arm.
My wife was earlier using 2 x 24" screens, I got the standard 2 monitor arm version and added 2 bracket (cos wife's screens cheap Dell ones without Vesa mounts). The picture above was when it was first installed and she was still using the 24". I upgraded them to 2 x 27" and so far it's been good. I also had to get another laptop arm to free more space on her desk.
Came across one of the laptop arm brands on Taobao

I really love this design, very sleek and has 2 segments so you can swing it out to make it closer to the edge of the desk where you are seated. It's more pricey but the mechanics are very good, very sturdy and well-constructed. You can also find some carousell listings selling for about 10-30% on top of the Taobao + shipping cost. If you don't want to wait, can consider getting on Carousell.
In the end I also got a monitor + laptop arm combo for myself. This version is able to support my 32" monitor.
