Billy, I totally agree. I've done some work with China for mass production strategies, etc on goods (requiring metal working) vs. in US. It's kind of funny that minimum batch acceptable there mostly is in thousands vs. hundreds here in US for similar things that need to be done. (and funny enough cost nearly same... so cost of real simple part for short run can be as high as 10x in US vs in China).
That 15% is actually from SixtyFiver's comment I just quoted and taking what he wrote at face value.
