Ice cream maker recommendations?

I don't know why he said not to use metal, but I wouldn't. Your skin will stick to the sides of the canister when it comes out of the freezer! Although I can kind of understand your line of reasoning, unless the metal canisters are insulated, I don't think there will be a significant difference in the length of time the ice cream will stay cold under the circumstances of the way you're using them. What you need is something in which the ice cream can be placed that provides insulation.

Edit: Well, what I mean is that the containers in which the ice cream is packed should be placed inside of something that provides insulation.
