Gary, I think you are getting a bit carried away here. I can't see that there is enough world market sales in specialist stepper motor driver chips like the TB6560 to make it worth there while doing a replica. Faking memory chips and consumer IC's as you identify maybe.

Anyway my Chinese driver with TB6560's works fine. The only criticism is the slightly inadequate heat sink and fan assembly but thats quite easy to upgrade and will only bother those working at full power for long periods.
