I have two combo machines. A Janome MC 10000 and a Janome Horizon 15000. I use both of them for embroidery but only the 15000 for piecing and Sewing. I love both of these and enjoy making quilt blocks, handbags, In-the-Hoop projects as well as embroidery blocks for Charity quilts etc.
I've always enjoyed the 10000 but the 15000 just opened up so many possibilities.
