The chrome parts available are definitely NOT all the same. The stuff from Asia is usually junk or bordering on junk. The NOS (New Old Stock) German stuff (like headlight bezels, etc.) will last and last but are getting hard to find and very pricey. If you can find new old stock VW parts they tend to be a lot better.
Beyond that, you really don't know what you're getting from anyone these days, and price, alone, is seldom a good indicator.
Sierrra Madre, Stoddard's and the "real" Porsche stuff is always pricier and is supposed to be better.....Sometimes I find that to be true, sometimes not.
Aircooled parts and Airhead Parts both have a lot of good stuff (those headlight chrome rings at Airhead are $18.99 each), as does Bug City in Berlin, CT. All good outfits but they ALL carry both the Chinese as well as German, Brazilian and Mexican parts. They usually tell you which is which and the prices vary.
Good hunting!
