It depends on what manufacturer you choose.  There are some that are bottom dollar, and they'll give you what little money you want to spend.  I'm in contract product development, and when you go cheap, whether it's here or in China or in Mexico, you get cheap.  On the flip side, if you select competent contractors there, you can get extremely good quality.  I work with several factories there, and they have everything from the most modern automated systems to the most manual labor intensive junk with yield rates below 85%.

You can get the same garbage here, but at much higher rates.
