I could easily argue that a spare engraving bit is a must have. Not having a spare engraving bit is like driving a car without a spare tire - if you get a flat, you're in big trouble. Treat the need for a spare engraving bit the same way. If your engraving bit chips or gets dull, you'll be out of business until the manufacturer can get you a replacement. If you just can't afford a spare engraving bit when you purchase your new engraver, make it a goal to get one in as soon as possible. The cost is minimal compared to the down time.
