I have the Brother PQ 1500S. It's super nice. The only cons I have are
1. Needle threader is the worse one I've ever tried to use.
2. The manual sucks.
It sews a great seam and machine quilts great. I did find out that I can't share an electrical reel off one socket with another sewing machine. It needs full power. The bobbin winder has to be fully disengaged for the machine to sew or you'll go nuts trying to figure out why it won't.
