Hi BusyLizzie, I like your name I had a Busy Lizzie doll when I was a little girl. I recently purchased the 740, less than a month ago, along with the straight stitch plate and the 97D foot. I bought it for the dual feed and the bigger harp space. The biggest adjustment for me is the 9mm width of the stitch plate. I have made two "complicated" quilt blocks on it and am pleased with the accuracy, I do sew slower on it than on my 530 which is 5mm. I do not use the guide on this one though and with my 530 I used the quarter inch foot with the guide. I am usually a slower stitcher though.. I am cutting fabric today sew my first quilt on it. What I do not like about it is that it is really heavy, but I am not planning on taking it anywhere, now that I have taken the guide classes. Hope this helps.
