Yes,every machine should come with one of those straight seam attachments. Aren't they great. You can also adjust it at an angle and you can sew great circles. Why don't all machine manufacturers come with this simple attachment? I know many of the beds are now made of plastic but they could still include this by reinforcing the underside of the screw hole with metal. I have grumbled about this with my new machine every time I have straight seams to sew. The necessary hole and attachment are so inexpensive to install at the factory why won't they do it???
