I have it and use it on a frame. I have only had mine for a few months and have quilted about 6 quilts so far from crib size to queen size. I have enjoyed mine very much and do not have any major concerns with its performance so far. I am finding that there is a real difference in how much lint certain fabrics and threads generate and I try to keep a close eye on the bobbin area and clean it out everytime I change the bobbin. I only thing I wish it had would be a bobbin thread monitor. My other Pfaff machine has this feature and I have come to depend on it. If you have any specific questions let me know and I will pass on any information I can. Good luck with your search.
