Totally agree with Keye as I have also had conversations with him re: what size and type Saw blade to use, also purchased products from him.I have found Mr. Iturra to be a fountain of knowledge and very willing to take time to talk with you about any problem. I talked with him about a problem and bought several parts from him, including a spring. When I received the parts there was an extra spring in the box along with a note. After we talked he was not sure I had bought the correct spring so he sent a different size at no cost so I would not have to wait for another spring if needed.
