Vince Basile's supinator machine 10000 moving parts , cost over $100k
''Here is the first image online of the biceps-supinator. This was invented by myself and built totally by myself in my engineering factory. I tried to sell the design to Nautilus and Cybex but they were not interested. So this machine has cost me over $100,000 to patent and build. Surely it is the most expensive machine ever installed in a gym.''
