I bought mine just as they were transitioning to the stitch regulator so it doesn't have one. They offered to put one on at a steep cost and I would have to send the head back to them. I said no thanks. I learned without it and I don't see as I need it. I would say it's your choice, if it is a perk you want fine, if you want to save the money that probably is fine too. I never regretted my purchase. Good luck.
