Looks like you emphasize PR too much, dofollow paid links from directories that pay to be in your list, and nofollow some of the directories that are actually offer a strong backlink. How can anyone take such a list seriously as your subjective use of deciding what is a quality directory is based on how much that specific directory owner has paid you?
The discussion here is not that PR is important or not, web-directories.ws is the best list out there, and its updated regularly and he announced that PR is updated.
