This is the one that I bought when I first started quilting about 1 1/2 years ago. I love it and have not had a bit of trouble out of it. Have made a lot of quilt tops with it but I do not do my own quilting. I send out my tops to have them quilted. This is from Sears and I would buy another one if I had too. I really like this machine. Make sure that you get the 1/4 in foot for it.
