If you are looking for a great computerized machine for quilting, the Janome 3160 is terrific! It has the automatic thread cutter, which is my main stay when piecing. It only weighs 12.5lbs. I take it to all of my classes. Go to the Janome website and do a comparison on this one and the Jem machine....this will give you the features side by side so you can choose.
