Thanks for the input, never had a spring go out like you mentioned. I do not believe the system is a dinosaur and I feel there is still demand for the system. As an owner of an Aerospace company I fully understand manufacturing assembly and distribution. I am trying to determine how many could be sold globally per year. Letís say 4,500 a year at $300.00. Comes to $1,350,000.00 in possible revenue with a gross profit potential of around 20%. This forum is just one avenue to find out if the demand still exists. I would find it hard to believe that I am only one who would still buy the clicker.
