Even with a longarm, I've heard that some people use a saddle type of seat on wheels on which they scoot around with so they can be sitting rather than standing. I have back problems, and I think that is the only way I could do a lot of quilting at one time. In fact, i think i saw that Sharon Schamber has one. I saw a Juki and a frame set up at one of our LQS and it was only(?) $5000 for the machine and frame. The frame was only 60" wide, but I make only lap quilts, so that would sure work for me. Unfortunately, that was a couple of years ago, so the price is probably a lot more now. Oh, well. I can dream!
