Are standing desk converters worth it compared to a full electric standing desk?

Across the reviewers we read, converters make sense if you already own a desk you like, want a sub-$300 entry point, or rent and can't replace furniture. Specialist communities on r/StandingDesk repeatedly note that for similar money you can sometimes buy a full electric desk, but converters win on portability, zero assembly on Vari-style models, and the ability to keep existing storage drawers underneath.
