I have the Brother 1500, so if you have any questons, feel free to pm me. I LOVE it, but my only complaint is the bobbin- there is no chime or easy way the view the bobbin. You find out it has run out of thread...by sewing. :x It is a super smooth machine, quiet, easy to machine quilt with. 25 year warranty, knee lift, an assortment of machine feet come with it. I don't use mine on a frame, I machine quilt with the extension table and the bulk of the quilt supported. You can use a stitch regulator with this model if you choose. Honestly, if I were you, I would let the bobbin be a HUGE factor. Machine quilting runs through so much bobbin thread. I didn't consider it when I picked it out, and that is my only regret. Also, I only paid $800 for my Brother. Not sure what the others are going for. Hope that helps you some, feel free to message me if you need to.
