I have a Viking Mega Quilter, which is no longer produced. It is basically the same as the Juki. Only sews straight but can sew pretty fast or slow. It's not the width of the throat, about 10", but the height also that really helps get those large quilts in there. It has served me well. I easily quilted an oversized king without a problem. The secret is to have a large enough table to rest the quilt on while you work.
