Here is a Chili's margarita maker. It will do all sorts of frozen drinks. It's basically a blender on steroids. It holds a gallon of your favorite drink and has an easy  pour spigot on the front. A cool option is that it will run on 120v house current or 12 vdc with the cigarette lighter cord, so you can take it camping. . I have never tried the 12v option. But I'll try to test it  before I sell it. I bought it several years ago and just don't use it. New they sold for 149.00. I'm not sure if they still sell them. It does make good margaritas.
