Drywall Master King Automatic Taper

Built around cleanup: the cover plates come off without screws, so stripping it down at the end of the day is quick. The internal push rod and side plates are stainless steel, the tube is hard-coat anodized, and parts are highly interchangeable with other major brands.

Available in Standard and Mini. The manufacturer lists the pump and gooseneck as required to run it; both are sold separately.
