A good deal of his information is invalid or misleading and should definitely be ignored (his "spin test" is completely meaningless). Yes you can get cheap carbon wheels. They probably come from the same place as expensive carbon wheels and perform similarly on paper. But what shouldn't be overlooked is the fact that when you buy from a company that doesn't have a public face, you buy from people who don't have to worry about accountability if something goes wrong with their product. A lot of the price tag on more expensive parts is paying for marketing, but a lot of it is also paying for quality control.
