We recently launched a site that is affiliated with a print classified paper. It charges for ads by word count and also charges for picture insertion and bold print in the printed version (we couldn't figure out an easy control for the online version). There is also a custom export that exports the ads for online and print to an rtf file for typesetting. We converted the blog to use as a service directory and plan to use comments for reviews.
It also features clickable rotating banner ads with click and impression counter which are managed from the admin dashboard.
