I purchased a used SEI drive for 300$ and after over 200 engine hours on it. It still runs great. Yes most of the gearing was made in china and assembled in the states. But, This is not the 60's. American made is not the quality it was, not even close. And china is not the end of the world. Most of you live by apple phones and products and yet all the components are made in china too. Hell my "american made" car is full of foreign parts. Not everything in china is made with poor specs. They can make good products that last. The quality only depends on the buyers requirements. And really, how long does it take to remove and reinstall a drive....... 10 minutes.....
