I have the 430 and the 440. (Long story, short, I inherited the 430.) I love the BSR but there is a learning curve. It is a great machine for piecing, and wonderful for applique. TIP: If you are having trouble with the tension when free motion quilting, thread the bobbin thread into the hole that is at the tip of the bobbin case, which is designed for embroidery. It helps get the tension right. Also, BSR 1 is controlled by the blue button. BSR 2 begins when you start moving the fabric and stops when you stop.
