The difference in the consumer quality and industrial quality boxes in mainly how well the drawers and slides hold up in daily use. For a weekend hobbyist the consumer box may be fine, use the same box at work where you open and close heavy drawers all day long and it won't last. If you are serious about continuing in this line of work then buy something good quality new or used. How would you feel if the doctor you went to see had a Wal-Mart blood pressure monitor? The same applies here; you are in a profession, strive for the quality that marks a professional and the durability your profession demands.
