You know i remember when i first got in this hobby my instructor told me if you cant afford to buy good equipment that is proven and safe then you have chosen the wrong hobby  , so many times we chose a cheap product and when it fails we get mad , well if you can't afford to buy the good proven parts and equipment that is your choice and you will pay the price of a plane or other damage , the choice is yours , but as for me i shall purchase tested and proven products  , confidence has no price you either afford it or you buy garbage !!!!!!!!!
