Cuisinart Mix It In Soft Serve Ice Cream Maker

Should I buy another bowl for a different flavor? My grandsons don't like the same flavor? Can it be emptied and used again right after?

Does this machine require purchase of a special mix, or can you make ice cream using a recipe for typical "churned" type product?

I have a regular ice cream machine at home, but am thinking of ordering this as well. Do you think it would be worth it?

how long does the ice cream last before melting after you make it?
