And keep in mind there have been repeated reports of Google employees saying links from directories can be okay. If there is a quality review process, which involves rejection of sites regardless of whether or not they pay, then it is more likely the directory is going to provide some SEO benefit. I would not regard link exchange directories as having a "quality review process". However, there are plenty of good directories that can provide some benefit by having a listing.
