These days I doubt that moving production to China is necessarily a bad thing for the consumer. It's bad for US and EU economies, but as far as the quality of the end product is concerned one could ague that the chinese version is likely to be equally as good and more consistent than the product made in the western world given the leaps and bounds China has made in manufacturing technology.
Take for instance an example from my other major hobby, photography. A while ago Nikon moved production of a popular but sepcialist high quality lens from Japan to China. I own the original verson made in Japan, and a friend of mine owns the newer version made in China. Technology these days allows us to make very accurate objective evaluations of optical equipment, and I would definately say that the Chinese varient has a touch greater resolving ability. There's not much in it, and what difference there is could be accounted for in terms of product variation. However, given that lens production requires a very high degree of precision, much higher than producing transducers does, it shows that the chinese are definately up to the job.
I also work with hi tech products sourced from China. 7 years ago we had an "out of the box" failiure rate of around 20% - 1 in every 5 units was effectively DOA. These days that percentage is now down lower than 0.1% - that's less than 1 in every 1000 units. Things have improved greatly within China's manufacturing industry, and to write off a product, especially a premium product, simply because it's made in China doesn't make sense these days. 5 years ago yes, these days no.
