What's the best machine for development?

Whats the difference between a gelato machine and an ice cream machine?

• I want to make pro quality gelato, but need to start by making it at home first without investing 3000$ for a machine. So is there a difference between a gelato maker and an ice cream maker? (colder temp? pressure? etc)

• Answer:

  This was a deliberate decision by Britton, because the manufacturer makes a different (and cheaper) machine for the type of ice cream found in the American markets. "It whips air into the ice cream,'' she said. Another notable difference is the texture. "The ice crystals that come out of my machine are a lot finer.''
