I understand it is better to build your links manually. Can anyone give a link showing a list of all the directories?
DirectoryCritic.com is very good resource. You can choose free or paid directories, niche directories, sort them by date or PR, etc.
i agree, directorycritic has huge list of directories. you can also visit the directory part of this forum where lot of directory lists get posted on a regular basis. just do a seach on DP for directory list and you will find MANY
Only fraction of webmasters pay for links in directories. This can be called a small advantage because these directories may have less links in total. However, many paid directories started as free directories. So some of them may have a lot of links too.
