What kind of domestic machine do you have? I like the frames but the small sewing space of a domestic machine makes the frames not so easy. There are the newer Pfaffs and a Pfaff Grand quilter (and I am sure some others) that are slightly larger than a regular machine. But if you have the room, some of the frames and the "groovy boards" can do pantograms very nicely.
Just another thought...I have a Handi Quilter 16 Sit Down machine. In the end, I knew I couldn't stand all the time to quilt. I still have to pin baste my quilts (uck) but I can sit and quilt quite satisfactorily even the largest quilts and have the large sewing space of a mid-arm machine. Price point is much less also. AND, if I ever want to add the full frame system, I can add the frame, table, Stitch Regulator and even the Pro Stitcher.
There is a new model out from HQ called the Sweet 16. Perhaps if some dealers still have the older model like mine, you might get a good price for one.
Have fun.
