I agree that there was some issues with poor quality chinese products, but that was in the past, things are changing very fast.
Have a look at a $2000 LG plasma/LCD TV... A top model, Korean brand, it's got a sticker that says, "made in China"! Soon, most japanese brands, european brands, etc, have a potential to be made in China, simply for the one reason - lots of factories, cheap labour.
I work as an engineer, and I find that making a same component from China, either mechanical or electronics, is so much cheaper than made locally and businesses love it. The quality maybe slightly inferior in some cases, but even so, it is still cheaper.
All your movie DVDs, majority of your PC components, guts of your entertainment electronics, your Sony Playstation 2.... they are all made in China.
China has the largest number of manufacturers in the world. With cheaper labour, majority of countries just cannot beat their mass production capabilities.
The benefit you and I get, is that these items come down in price very fast, because of their mass production in China.
Support is a big issue. Well-known brands have more experiences in dealing with consumers and already has a good systems set up for customer services. They will have dedicated people/system for dealing with customer complaints, where as, less-known brands may not.
As for my PCUT CT630 issue, i think it's resolved, it's been cutting away signs beatifully. Thanks again.
