I had a "BOSS" and got tired of the lever and other problems, parts breaking, that had to be sent back to the manufacture to be replaced. Aluminum gears that would break or strip. Needle guide that would break. and so on and so on. sold it, got most of my money back, bought the cobra from Steve and after some education and laughs, this thing is a piece of art itselt. love the out come and hope I sew enough to wear it out. Thats a lot of sewing.
