The Empress which I was told was made by Tin Lizzy comes in either the sit down or frame/stand up model. The throat area is 6"X18". The thing that I liked was that it has double capacity M bobbins, which are larger than the standard home machine uses. Also comes with a built in bobbin winder. The frame model comes with stitch regulator. I have never seen a sit down model from any of the manufacturers that has a stitch regulator. I guess that is the difference between moving the quilt under the needle in the sit down opposed to
moving the head of the machine over the quilt on the frame.
