I just bought the King quilter 18 inch to put on my Grace Majestic frame. I had used a babylock Jane on it but everyone is right about the space being small especially after rolling the quilt. So far I like the King quilter but I haven't used it much yet. The machine was around $3,000 from Sewing Machines Plus. And I can add computer to it if I want later on.
It seem to be a good machine for the price .
