If you look at the bottom of this machine you would see why it can't be put in a regular sewing machine. It's been a while since I saw it, but I remember something about the bobbin area being more complex. That being said, I thought I'd love to have that machine until I saw the price. I thought it was stupid to put that price tag on a one stitch machine. If you can buy a cover stitch machine for what they are, and that looks more complex - the sashiko shouldn't be anymore expensive - in my mind. But then the Babylock coverstitch is much more expensive than any of the others. I always thought Babylock shot themselves in the foot with this machine. If they had priced it at $1499 or something like that many more would have been sold.
