I've made a list with more than 6.600 directories.
This list contains:
- i've included link updates at PR at each acces.
- i've included Alexa Traffic Rank (Alexa Traffic Rank is a very important factor by which you choose the directory)
- i've included Alexa Links
- i've included the sort by PR (Google's PageRank)
You can find the list here:

I hope it will be much usefull like this.
Have fun!
