Recently bought a ninja and there is no going back. I'll never use a crappy blender again.

Anything else like that?

Some are expensive for filtering reasons. It can take some engineering to build HEPA or similar filtration along with seals that actually have the filters work, plus managing motors or filter designs that aid in the high speed airflow needed for a vacuum.
