I paid Stick and Rudder for my demo flight. I believe that Kitfox and Stick and Rudder have an arrangement so that you fly with Stick and Rudder. On that flight, I was taken to the factory and was given a tour. I only paid for the rental and instructor for actual flight time. It is WAY worth it. Bring your check book cuz you will likely sign one over as I did. To be honest, I signed before I flew but I knew in the first 5 minutes of flying that next day, I would never regret that purchase. I had to rent a car to tour the factory the first day as it was raining but we still went back and landed at the factory to say hello on the next day.
