I feel this exact same way! Or they charge an arm and half a leg to get a D loop tied on. For these reasons i have gone to doing all my own work, yes it takes me awhile watching videos but dang does it feel good when your bow shoots spectacular and you did it all yourself.
Amen. I stopped in a shop this spring to pick up some nocks and his sign with pricing had $20 for a d loop install. I about fell over.
