If you believe that chinese electronic components are terrible, just mess around and buy a "chinese imported welder". If the thing even works out of the box it wont for long, and the freight to send it back for a "free replacement" is more than it was worth to begin with. The solution to the issue is to demand higher quality to begin with and not shop merely by price alone. I have made this mistake too many times and still occasionally do, but for the most part I look for where it is made more than what the actual price tag is. Remember, "If it is too good to be true....it is...." Just my .02.
