Sub-Zero is without a doubt one of the finest refrigerators money can buy. They operate quite differently from a regular refrigerator. Sub-Zero refrigerators have dual compressors to operate the freezer and fridge while most refrigerators have a single compressor that powers both. However, whether they are appropriate for you is a matter of personal preference. Think about how long you'll be in your location. If this is your ideal kitchen and you want to use it for many years, the price may be justified.
