You can always sit with the long arm and do sections. I like that you baste the quilt on the long arm versus basting the quilt and then sitting down to quilt on the sit down. My vote is for the long arm if you have the space, the biggest frame with a good throat opening on the machine 18-26 in. seemed most desirable to me. I ended up with the machine that felt the lightest to operate to me, Innova.
