The Workstream by Monoprice Dual is the budget gas-spring pick: PCWorld names it the best budget dual arm, noting it costs about four times less than the Ergotron LX Side-by-Side while supporting monitors up to 34 inches and 19.8 lbs per arm. Its steel-and-aluminum build is sturdier than all-plastic stands, but setup is awkward and the motion isn't as smooth as premium arms. For a low-cost full-motion dual setup, it is a sensible value choice.
- — Roughly four times cheaper than the Ergotron LX Side-by-Side

- — Steel-and-aluminum construction is sturdier than all-plastic stands
- — Setup is difficult and operation isn't as smooth as premium arms

- — Finish and feel are clearly budget-grade
