I have the Janome 12000 and love the features and the multi size hoops. It comes with various feet, I think I have 20 more than I will use. The decorative stitches, the quilting stitches,and the embroidery function is awesome. I have now used the quilting function on a quilt by placing the fabric on top of the hoop secured by bull dog clips normally found in office supply stores.
My Viking Emerald 118 , I love equally as it's a work horse for sewing and piecing but when it comes to embroidery and quilting, then it's the 12000.
I was lucky enough to try out various models and the Janome won out. Good luck on your adventure.
