How does the 'quality control' of current supply compare with that of 2001 ?

We don't really know. On average I think it's fairly obvious there's been considerable improvement since Far Eastern machines first appeared in the 1970s. Early magazine reviews are all negative. Today much of the comment reports minor problems rather than major ones, though major issues do still occur.
The centre of production is continually changing. It's moved from Taiwan to mainland China who are undergoing an Industrial Revolution. Their industrial base started primitive and is evolving rapidly. At the moment it's a mix of high-end and low-end production methods not dissimilar to the UK in 1950. (Shipyards doing welding next to shipyards using rivets, modern steel works next to a Victorian Iron Foundry, Jet Aircraft being built by men driving Austin 7s etc.) China faces competition from countries like India who have a similar mix of world-class and primitive engineering.
Making hobby lathes is highly competitive and profits low. It must be very tempting to use 'nearly good enough' castings rather than rejecting them and to not slow production by fixing small faults. On the other hand machine surfaces are accurately made with grinding machines. Early problems with motors, bearings and electronics are mostly solved. Gears and other components are competent rather than polished. However, lathes appear to be assembled in a hurry with minimal attention to cosmetic details. The end result is a mixture of mostly reasonable lathes with some exceptional examples, and some bad. For industrial use, the quality process would reject the bad outright and uplift the reasonable to a specification, paying considerable attention to the details. This is expensive!
I don't think enough lathes are made to justify the quality techniques used to make cars and electronics.
Once hobby lathes are finished, I guess 3 things happen:
- The rejects are sold off locally. It's possible that that these end up on ebay or similar. The risk of getting a dud from an unknown source is higher.
- Some Western outlets pay a premium or otherwise apply leverage to get the best examples for their customers. (Based on fewer moans about them I guess that ArcEuroTrade, Warco, Axminster and Grizzly at least do this to some degree, perhaps also checking a little more carefully before shipping. It doesn't guarantee complete satisfaction, but it lifts them above the average.)
- Other outlets may simply pass on reasonable examples, perhaps after a superficial inspection before shipping. Most of these will be OK, but the risk of getting a clunker will be higher. Your protection is that they will change it.
Customer service is another variable. Company policy might be to resist all but the most justified complaints, or it might be to respond positively even to nitwits and time-wasters. Policies and attitudes to customers change over time and even the best run organisations drop the ball on a bad day. You might ring up when most of the staff are off-sick and the untrained temp has a filthy headache! And there's a reason why most firms don't allow engineers to talk to customers.
Generally I think quality tends to rise, but there are many reasons why it's not universal. For example, as the pound has lost value in recent times, and because UK vendors have to keep prices low, there's likely downward pressure on quality at the moment unless the Chinese have improved productivity to compensate.
I'm guessing really. We would know more if everybody shared their experiences good and bad in a standard form, but we don't. It would also be interesting to be a fly on the wall at, say, ArcEuroTrade to see how Ketan does business and to visit his Chinese suppliers and their facilities. I'd expect most of what goes on behind the scenes to be slick, a fair bit challenging, and some of it heartbreaking. The world's like that.
