Before we go any further let me say that some of our products are manufactured in China. We try to do quality testing on every item we sell no matter where they are made. Recently we have been approached by several manufactures in China that want us to buy from them at a greatly reduced prices. We have purchased a number of items at random and tested them. All have been of inferior quality or non-functional.  Not saying that you can't find a quality part for a greatly reduced price, just no likely. This is a highly competitive business and most distributors are in the same ballpark as far as price is concerned.  If the price is considerably lower then what you have been finding, you may get less then what you pay for.
