Chocolate/Candy Funnel

I've been making molded chocolate by ladling it from the tempering machine into the molds -- messy and wasteful. I recently learned about chocolate funnels, and discovered two kinds.- a simple metal (or really cheap plastic) cone with a tapered wooden dowel to plug the hole in the bottom and control the release of chocolate- a more complex cone with a trigger-operated spring valveThe trigger funnel is less expensive, and looks handy, but is it a good idea? Anyone have any thoughts or recommendations?Many thanks,BrianKakao Chocoalte
