How much should I spend on a standing desk?

Across the reviewers we read, sub-$200 electric desks like FEZIBO and ErGear are widely considered acceptable for single-monitor home-office use, while specialist communities consistently push buyers toward $400+ frames (Uplift, Desky, Flexispot Pro) once heavy multi-monitor loads or tall users are involved. Expect more wobble at full extension at the budget end.
