I've never done a full test of many types of ice cream makers. I've personally owned this Hamilton Beach Ice Cream Maker. It requires you use ice and rock salt and is very consistent. It makes great ice cream. We also own this Cuisinart Ice Cream Maker that does not require ice or rock salt. It's a little more expensive but the process is slightly easier. However, if your canister isn't fully frozen before you begin your ice cream won't set.
