I bought an electric one a few years ago after watching Alton make ice cream and sorbet... it died, didn't even make it through my first batch of sorbet
Then I found a hand crank model with a freezable core. I've made frozen yogurt using Alton's recipe but changing it to blueberry, one of Emeril's ice cream recipes (chocolate) and orange sorbet again following Alton's recipe but changing the fruit. All were excellent, if I do say so myself
I didn't make any last summer because my freezer was packed full and didn't have room to put the core in
