Take a looka a device called a PC Quilter and also the "Max Throat" attachment for it. You can use the HQ 16 (or almost any other machine and almost any frame that you already own with that...it is a fully robotic and copmputer-controlled device that will do anything that you want to do automatically, without errors or back-ache, while you do something else as it works. Cost?..under 4 thousand with a new frame and a new machine, if you need them. But the best part is that you may need only the PC quilter itself, for about 2500 dollars. the device is a mororized X/Y axis carraige that mounts your existing sewing machine and fits your existing frame. The Max throat is an automatic attachment that rolls and unrolls the quilt as the sewing machine moves...so its like having a full-sized industrial frame the size of a king-sized quilt. Google the name for lots of videos all about it. It is the cats PJ's..and it is a cheap and very good system of high quality.
