I have a Bernina 440QE with the BSR and have been able to FMQ after the usual learning curve. I do find the throat is tight if you want to do a larger quilt. I have purchased a 750QEE recently but it is still in the box waiting for my new sewing studio to be completed, hopefully by next month. It has built in embroidery while the 440 must be connected to my laptop for embroidery. I plan to keep the 440, it is a wonderful machine but the 750QEE has everything I could wish for, and it has the new large bobbin.
