I too my looking for a lightweight machine for classes and retreats. I'm not sure what I'll end up with in the end, but if I get a Featherweight, it won't be my only lightweight machine. I taught a quilting class once which required zigzag. Neither the shop owner or I gave it a thought to put that in the course descriptions and two ladies showed up with their FW -- needless to say, they couldn't make the class project.
