I agree. You're already paying what some consider crazy money for a sewing machine- an extra $150 is not a ton. Besides, consider it Murphy insurance. If your life is like my life, if you DON'T get the zigzag within the next month you will have a need for it, and the cost to have someone else sew it will be higher than the cost of the feature.
