I think if you never had one you can't miss it. My machine does have it and I love it. I really never have not used it. I like it because I can stop and think about what I'm doing or where I want to go next without having to turn the machine off or the stitching (what ever you want to call it). They say the machines run smoother with it off and it does, but it's also another learning curve you have to go thru. Just me 2 cents worth.
