Be sure to measure your space and consider whether or not you need an open flame, radiant stovetop, gas range, or induction cooktop. You should also look at how many burners you need. As well as what type of ventilation system you have installed (ducted venting vs natural). Many commercial ranges include all safety features such as automatic shut-off systems for stoves with hot surfaces and proper equipment use warnings. The final thing to keep in mind is maintenance: make sure you read any warranty details before making the purchase.
