Immersion blender, multi speed, Broan. Don't have to wash a blender container EVERY time it's used. Just get a bunch of sturdy 32oz plastic cups, blend, rinse blades, walk away with shake. Blade attachment works well w/ crushed ice and split frozen strawberries and raw oats.
EDIT: Even if the removable blender attachment reads "Not Dishwasher Safe" put it in the dishwasher every once in a while blades up. I hand wash it most of the time.
