Has anyone played with the new Rosco Vapour line? The Vapour Plus is cute and reasonably priced, but is it loud? Loving all the manufacturer videos online, but none ever have the sense to cut out the background music -- I want to HEAR the damn thing before I buy it. Also looking at Ultratec's Premier Fog Effects Generator - anyone know how loud they are? Any recommendations on the quietest DMX fogger on the market would be greatly appreciated!
