I have 3 machines, a Brother and 2 Pfaffs.
My Brother is a low end which I take to classes. (It doesn't mind being carted around) I love the drop-in bobbin and it does a better job on some of the applique stitches, particularly the button-hole stitch.
My regular Pfaff (I think it's called a Quilt and Sew) has the built-in walking foot, needle down selection, low bobbin indicator, a nice 1/4" quilting foot for accurate seams, and a stitch-in-the-ditch foot for straight line quilting. That is really my work horse.
Then I invested in a Pfaff Grandquilter which has a 9"x6" Throat Opening for quilting. It is a mechanical machine that requires oiling and it ONLY goes forward and backward (but it does so VERY fast). It has a bobbin winding system that does not require you to remove the sewing thread.
I plan to set it up with the Handiquilter Frame (that has been patiently waiting for years) and the Quilter's Cruise Control (that came in last week) and use it exclusively for the quilting part of it all.
I'm excited for you. Have a blast.
