It's worh noting that the country of manufacture does not necessarily have any bearing on the quality of the frame. There is no reason why Chinese or Taiwanese welders are any less capable than American welders. They might be paid less, of course, but they probably have more bicycle frame welding experience now than most welders in North America, considering how few bikes are actually made here.
Materials are another thing, but I think you'll find that decent-quality Chinese and Taiwanese bikes are being made from the same quality materials as bike in the US, Canada and Europe.
So don't get hung up on brand name or country of manufacture. If it's a crummy bike, then it's a crummy bike -- and it would be just as crummy if it was made in Pittsburgh.
