Well now they have a real machine that you use to sew it on with I am not sure how good they work but they are out there and some people really love them.
I prefer to hand stitch mine down on the back side.
I have seen the one Bernina has and it is expensive I think then you need to purchase different size attachments for the different widths of the bindings. hope this helps check it on Bernia usa web site.
