.My choice for a light weight Janome for quilting, piecing, etc. is either the 3160QDC or the 4120QDC. They weigh about the same as the Jem but are full size and designed for Quilters to take to class or anywhere else. Love my 4120 except it only has one light so I have a folding lamp I take with me. I have other Janome machines and I find it very easy to switch back and forth from them to this one. Plenty of features and feels like a full-size except for the weight.
