I have 2 favorite Web Directory Sites and they are as follows:

 www.best-web-directories.com    I really like this site. Although they only have around 12,000 directories (including 2600 free general directories and a list of niche and regional sites) that's still plenty enough to keep me busy. For those of you who don't have time to submit to them yourself they have a manual directory service submission. The best part of that is they can submit them slowly just the way google prefers.       

This is another this site I think is really cool. They say they have the largest list on the Internet, over 26,000 Directories.  

www.directorysnob.com

  It lets you keep a list of the sites you already submitted to. It also breaks them down into different types (i.e. real estate, financial, etc...). It also sorts your list by URL, Alexa, PR, Type of links offered, script and language.    I prefer to use best web directories for my Lake Homes website because they suit my needs the best. Let me know what you think!

One last tip...when you do submit to Directories do it yourself if possible. Also submit slowly and continously. Submitting 10 a day is ok, but do not submit 200 in one day and do not use link farms!
