What web directory script do you recommend?

Thanks.

http://www.phpmydirectory.com/

anything lighter than phpmydirectory?

http://www.softbizscripts.com/link-directory-script-features.php perhaps?

http://phplinkdirectory.com

A lesser know free directory script is indexscript.com
I believe its less heavy then phplinkdirectory

you can also try the free version of
freephpdirectoryscript.com
