All that we can do WRT Clausing is hope. And continue to buy what parts we need from them. The problems with the Chinese built machines are two fold. First their quality control standards run the gauntlet from excellent to egregious. The more that you pay the US supplier for the same machine, generally the more likely it is to have been built decently. Secondly, they seem to have bought into the auto industry's new model syndrome. Which includes making sure that as many parts as possible do not fit older machines. Back when Chinese made usually meant Taiwan, that didn't seem to be so often the case. I have an Enco drill press that I like. I bought it new around 1980 or so. Up until about 2000 I could still get any part for it. Then the factory burned and wasn't rebuilt. A year or so ago I bought from Enco what was supposed to be the replacement model. I unpacked the box and discovered that everything in it is lighter, smaller, thinner, or all the above. I put it back in the box but had waited too long to send it back. If anyone needs a new 15" 2MT spindle bench drill press contact me off list. Anyway, my second point was that parts availability will cease much sooner than in the far future.
However, if you want something that you can use out of the box, then you are probably better off going Chinese. Just don't buy it from the cheapest source and don't put off making sure everything on it works properly as soon as you get it.
