I don't believe you could adapt a singer buttonholer to the Bernina. And finding a machine at estate sales or garage sales is a good choice. I have found several vintage machines that sew perfectly at garage sales and for little $$! I am always looking for vintage machines when I am out and about garage sailing.
I'm a little confused about the OP asking why you have to push a lever for reverse. I'm not sure why that would be odd. You're gonna have to do something to tell the machine you want it to go in reverse. Sewing machines can't read your mind. Yet! A lever seems as good as anything.
