I have the Bernina 440QE with the stich regulator and the embroidery module my favorite is the stitch regulator works wonders for free motino quilting you can never go wrong with a Bernina have you looked at the 830
it is a big machine with a big price like 10,000 dollars on sale and it does not do much more than the 730 as far as I can tell but does have more room for a big quilt Good Luck with whatever you decide
