My mom gave us a hand-crank Donvier ice cream maker she picked up at a garage sale many years ago and to this day we use it all. the. time. DH especially loves it and will happily sit in front of a TV show and crank away for the 15-20 minutes or so it takes. It's not big so it doesn't take long to freeze the ice cream (especially if you start with cold ingredients) and also doesn't make too much, so we can eat it all in a couple days which we like. And it's a great way to try new flavors. In a bit he's going to be making pawpaw ice cream from some pawpaws we picked today.
I think we use it a lot more than we would a bigger ice cream maker with a lot of parts and that plugged in. Part of what we like is its simplicity; it's so easy to put together, use, and clean. We just tuck the canister in the back of our freezer so it's always chilled and ready to go when the mood takes us.
