In2 covers the dual action range at a sensible price. The DA9 V2 is the smaller throw machine for coatings and detail work, the DA15 V2 at 15mm is the general purpose choice, and the DA12 Mini handles pillars, bumpers and shuts.
The forced rotation machine is the one to reach for when the paint is hard or the defects are deep, because the pad keeps turning under pressure instead of stalling.
