The "Margarator" is a $110 blender with a spout on the front, designed to make margaritas and other frozen drinks — and only that. While I'm sure it pulverizes ice with the best blenders, I'm a little taken aback that something so specifically tailored for one purpose exists when a perfectly good multi-purpose equivalent is likely already in the kitchens of most potential customers.
But on the other hand, the MSB-585 — it's just one of many Margarators from Nostalgia Electrics! — has a car plug to let it run off DC power. Can your KitchenAid do that? (Asking "But why would I want it to?" is not allowed.)
I discovered this particular model via Margarators.com, a strange site that exists only as an index of various margarita machines.
