I have an older mid arm machine (Pfaff Grand Quilter) on a 10 foot frame. I wanted to use it for pantographs and large designs, but I quickly realized that I was severely limited by the lack of throat space. The finished part of the quilt rolls up into the throat area leaving only a small area for you to work. It sews beautifully as a freestanding machine off of the frame. I plan to set it up on a table and to use it for freemotion and walking foot quilting. This machine has feed dogs, unlike some of the newer table models. You need to decide what your goals are and your budget. I jumped into my decision too quickly and did not get what I had dreamt of.
