Spending $80 on something a 5 cent nut can do just as easily is senseless to me but I am a tightwad and always trying to figure out how to do the same thing as the rich guys but for cheaper.
Oh I agree...just don't want to lose a 5 cent nut at 7k to save $79.95. hopefully since it's such an easy design someone else will come up with a competitive piece.
