Business Directory Script

[soulslayer]

What's your preferred biz directory script? Looking for something that can handle a local set of listings, maybe up to 500 or so...searchable, and that will allow signups and edits by the client themselves.

Looking also for the script to show a 1 page listing for each client, with ratings info, user input, etc.

Needs to allow ad placement and other links and sections (news, weather, etc).

Thanks
