If anyone ever gets to the electronics market in Shenzhen,China it is unbelievable. Every electronic thing under the sun at a fraction of the prices. Some are originals, some are copies and some are just unbadged originals (same manufacturer, but maybe failed QA checking on cosmetics or something). Obviously you can buy something that ends up to be crap, but at those prices it doesn’t really matter. Lots of component parts available there also.
