This machine is more industrial-minded. There is a large harp (brochure picture can be a bit deceiving - need to see it in the store), thread cutter, scissors, needle threader (no problems - works every time), some very nice decorative stitches(not embroidery machine dense, but alphabets are nice for labels), & I really like the "lock-stitch" button (especially when using your decorative stitches).
What a work horse ! ! ! My speed control is set "wide open" (up to 1600 spm) when doing repetitive piecing, mindless strip sets or strings, HSTs, paper piecing, etc.; I bring it down a bit when doing wearables & artsy stuff.
But my 2 favorite "bells": (1) the independent bobbin motor: it's great to keep piecing while your bobbins are winding & (2) retractable thread guides (along with the vertical spool pins).
I'm lovin' mine . . . .GP
I have the sister machine, Babylock Serenade that I adore. I upgraded from a Pfaff's 7570 which I also still have, just don't use as often anymore. The Serenade is my Pfaff's on Steroids, more bells and whistles!
