In my experience, the biggest setback to dealing with China, and electronic components, is the amount of counterfeit components in the market. It is difficult to find that 'diamond in the rough'.
I have seen a $1.00 part that physically looks just like a $5.00 part, where they remove the markings on the chip, and stamp them with those of the more expensive chip.. and sell them at the higher price, thousands of times over.
There are way too many domestic 'suppliers' out there that quote their 'stock' from unreputable sources overseas as well, claiming that the parts are 'their stock'
I hope for the future that there is a solution to the issues that we have with components sourced in China, but I think as one of the previous posts mentioned, by the time this comes around, we'll be procuring from other countries. From what I read lately, India is on the rise.
I would be curious to know if anyone has had any experience in dealing with acquiring parts / components from India.
