Best Directory Software?

[Cholo]

Anybody here have any experience using directory software?  I might be putting one together soon so I'm starting to do a little research on them.  Looks like there's a couple nice ones that are paid.  Wondering if anyone has used or is currently using one they like, especially if it's free/open source.

What exactly do you mean by "directory" software?

I mean a web directory.  Hard to explain I guess but you'll know what i'm talking about when you see it.  One example is like what DrHouse posted above.  Another one I've installed is phpweby, but support is horrible and documentation is worse. 

Thanks for the link DrHouse - the really empty support forum scares me away though.  Maybe I'll try it anyway as I've almost had enough of this phpweby script.
