I heard from a friend that is on her and I work at my local field/store with that someone on here posted a do it yourself project for a trigger similar to the HAIR. I did a search and couldn't find it. I heard the cost for parts was only like a 100 bucks or so. Any information would be greatly appreciated as I really want to find this and try this.
