I believe all of Nashbar's frames are from Taiwan ... and just about everyone else's frames are either from Taiwan or made in China for companies based in Taiwan (so your "frame from Taiwan" is pretty likely actually from a factory in China.)

Of all that you listed, only Kinesis is familiar ... but so long as you are buying from an actual company with a factory, a website, and a history, you are likely getting a solid frame.

Pretty much the only way to get the latest cutting-edge technology is to buy from a major manufacturer--they do the R&D and patent their latest stuff. The rather generic frames you buy from those other companies are likely two years' ago's tech (or the same level of tech you'd get in low-to-midrange frames from those major manufacturers)... and absolutely excellent, light, strong, and wroth the price and more.

I purchased a Chinese CF frame based on advice from many people here and over at Weight Weenies and am completely satisfied. I am sure whichever frame you buy from whichever Taiwan company will be just as good ... and maybe identical. Just do a little research to make sure the company has been in business for more than a couple years.
