But guess what? Virtually every blender has a "Crush Ice" button. So instead of buying a massive, expensive kitchen appliance, get a multi-purpose blender, like an Oster Reverse Crush counterforms blender, or, if you want to splurge, a Vitamix (which, admittedly, is more expensive than a margarita maker, but is damn more useful). It even has a "Frozen Drinks" button. Just add the ice right alongside your margarita ingredients and blend away.
