I still use a cheap frozen-canister manual...
made by Donvier, 1/2-quart size. Last time I looked I could only find a 1-quart model. You put the canister in the freezer a day or so before you need it (we keep ours in the freezer all the time, ready to go) then you just pour your ice cream base into it, slip in the paddle, and give it a turn every couple of minutes for about 20 minutes. No ice, easy cleanup, no strain on the arms. You can carry it around with you, take it outside, use it during a blackout. Makes good, creamy ice cream which you can freeze in another container if you prefer a more solid ice cream.
