Best script for selling ad space?

[RadiantX]

Anyone have any recommendations for a banner script?

Something that can create user accounts, allow the user to change his banner and URL as they please.

I can set the account to be active for X amount of days...

There are also lots of WordPress plug-ins if you are talking about blog ads.
