Yeah, I think their dual arm is a better deal at 48 right now but in general the Monoprice ones are a bitter better quality than the Ergear and Huanuo's posted more recently.
I have a 3-arm Monoprice and a 2-arm Ergear and the ways that the Monoprice is nicer: the attachment at the monitor can rotate 90 degrees (vertical), the adjustability of the gas spring is smoother/more precise, the cable management is system is tool-less, the desk plate is more robust, and the finish is nicer. So you get what you pay for in my experience.
Monoprice Smooth Full Motion Dual Monitor Adjustable Gas Spring Desk Mount - Black For Large Screens, Supports Up To 34 inch Monitors, Max 19.8 LBS Weight Per Display - Workstream Collection https://www.amazon.com/dp/B01J6KMNOK/ref=cm_sw_r_cp_api_fab_q5lGFb55BTRSS
It’s just one. I use this link from amazon: Monoprice Smooth Full Motion Dual Monitor Adjustable Gas Spring Desk Mount - Black For Large Screens, Supports Up To 34 inch Monitors, Max 19.8 LBS Weight Per Display - Workstream Collection https://www.amazon.com/dp/B01J6KMNOK/ref=cm_sw_r_cp_api_i_jI-XEb8VSMMGK
It works on monitors up to 34 inch that’s the only monitor mount that works with my 34 inch monitor and not 300 dollars and easy to build with instructions. Only 70 dollars
I actually have these: https://www.amazon.com/Monoprice-115525-Monitor-Adjustable-Spring/dp/B01J6KMNOK/ref=mp_s_a_1_3?keywords=monoprice+dual+mount&qid=1552957320&s=gateway&sr=8-3. They're in black. Not that it matters anymore since you bought already.
Haha I finished it 2 am this morning. I was definitely smiling going to bed.
Monitor arm is https://www.amazon.com/gp/product/B01J6KMNOK/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 and its the Dell dell U3419w
I don't have any complaints after using this one for 5 years:
Thank you!

is this it i am based in the uk :) https://www.amazon.co.uk/Monoprice-115525-Monitor-Adjustable-Spring/dp/B01J6KMNOK
Its the Monoprice 115525 Dual Monitor Adjustable Gas Spring Desk Mount (15 to 34 Inch) on Amazon. https://www.amazon.com/gp/product/B01J6KMNOK/ref=ppx_od_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 its the only option I could find that would support the weight of my 34", dual monitor and had multiple points of articulation.
It clamps on and is solid/strong enough for my two monitors (27" and 24") I like it.
Is it similar or better to this one I found?

Also clever repurposing of a baseball frame!
I have a monoprice one too and can highly recommend it. This is the one that I have. It seems to have enough space to potentially fit 2 34" curved ultrawides next to each other.
