I got a Bailey's Pro 15 about 4 years ago. I will say there is a big learning curve, but I would imagine that applies to any quilter one would buy. When I was at the point of wondering why I got it, I started calling the company and the gentleman was fantastic. He walked me through everything trying to figure out what I was doing wrong. It basically came down to the wrong needle size and incorrect bobbin tension. I love the machine. It doesn't have any bells and whistles, is a basic quilter, but it does come with a stitch regulator. My problem is controlling my own movements.
It is a workhorse of a machine. I am so happy that I have it.
