I have a Unity and love it, I also have a Katherine I sew on when I'm embroidering on my Unity, but I do my FMQ mainly on my Unity. My Katherine is great for classes, I only take my Unity if it is an Embroidery class. The size of my dual feed attachment took a little getting used to, but it works so well and I love it now. The Destiny & Destiny 2 have some very amazing features, and I would love to upgrade, but I'm saving my pennies to purchase a Coronet midarm ❤️
