The 380 extends the features on the 330 adding, amongst others, Bernina's FreeHand system. This knee lever allows you to raise the presser foot and lower the feed-dog without using your hands! Yes - this sounds simple but it ensures the fabric doesn't slip and gives you the ability to guide the fabric accurately - especially when turning. The 380 also includes an extension table for those larger projects and the mirror function enables you to automatically use the built-in stitch patterns in mirror image.
All in all, these extra features combine to provide amazing price/performance of this top machine of the 3 series.
Delivery is usually within 2-3 days and all machines come with a free 1-hour lesson.
You can see more details about the 380 on the Bernina web site.
