Rich, I am guessing you saw a demonstration at the show. If the jigs worked for them they will work for you. Yes, there is a learning curve with any tool, so it is best to work with some cheap wood at first. Once you are getting the results you like, then switch to more expensive woods. I still build a proto type of my projects from pine before using an exotic or hardwood. This allows you to learn anything special about the project before you commit big money for materials.
