I debated for a long time whether to get one because they are so expensive for a Bernina sewing machine. I found a good deal though and went ahead and I love it. I didn't see a huge amount of difference in my stid but I'm sure the quilt sandwich goes through much smoother and I didn't have to rearrange my fabric as much. Go ahead and try one, hopefully you won't have to pay a fortune , I understand they aren't very expensive for most machines.
