Components are actually one of the three categories of things I order from China. The other two being cheap trinkets and casual clothes. China-ordered components come from the same factories anyway, trinkets are binary (they either work or don't, not much space for quality difference), and regular clothes are crappy throwaway items regardless of where you buy them.

Anything else I consider too risky. In particular, I never order consumer electronics from China (unless I explicitly go for a particular Chinese brand). The crap quality is not worth the price savings.
