Can anyone suggest a link directory script, with the options of free listings, or paid listings (bold text, featured spots, etc)

Ive been searching for a while now, but cant find anything I like.

Check out www.hotscripts.com :)

Had a look there for the last few hours, but I cant seem to find anything I like.

Maybe this (http://phpwebscripts.com/linkupgold/index.html) is what you're looking for.
