It was demonstrated on the babylocks crescendo which is the babylock version of my brother machine. Regular 1499 at my dealer without table, it was on sale for 1299 with table included and overlay. The table is 300 by itself so I felt it was a good deal, and am working for overtime twice this month and all of the holidays through october so felt it was the right time for me to buy without having to add onto my machines monthly payment. During the demonstration it didn't seem jerky, the stitches came out nice and even. I think there are different settings on the stitch regulator and learning curve as with anything new you have to practice and learn the different settings. From what I have asked some of the sweet 16 owners say it is nice but there is a learning curve. They didn't say anything about it being jerky, just that there was a learning curve with it. I won't have it until october so won't be able to give a full review of it until then I have 6 months to pay it off
