Do I need a powered drain auger or will a manual one do?

Reddit threads on r/HomeImprovement and r/Plumbing repeatedly suggest starting with a sub-$30 hand-crank auger for small pipes and short runs; step up to a drill-driven or cordless powered unit if you have recurring clogs or longer pipe runs. Full 120V drum machines like the Ridgid K-400 are overkill for most homeowners and are typically recommended only for landlords, multi-bathroom homes, or semi-pro use.
