The problem with Chinese parts, in the realm of our hobby, is that most of it is cheap. Why? Because we are cheap, not because it’s from China. If you pay the same price for something made here, it will be cheap too.
It is not a conspiracy. It is the natural business progression when making old, low volume antiquated parts and selling to retail consumers.
The good news is that there are still good rollers lifters out there for us. They are not $400.
I’m with 1wildRT. I’d gamble on a SFT verses a low cost roller set up.
