Any of the Danfoss jobbies are the disciples (bloody krauts).
National Luna win because of the construction and insulation and are the Rolls Royce.

The Danfoss brigade come third because of lower power consumption of the compressor and either stand or fall due to the cabinet construction, insulation or features
