Quality Rankings?

[tjen]

How would you rank the following CD factories in terms of their CDR qualities today? (These names are mainly from the middle to lower quality group in the article.) It seems that many of the lower quality factories have improved their quality somewhat and I was wondering if their improvements are such that the quality gap between the best and the worst is significantly smaller than before.
