I've got Steven Zahm's pro version CMAP template of the Connections plugin. The free template by itself is amazing, but the pro template is simply gorgeous and adds some features that make the plugin extremely valuable for anyone needing a professional looking directory. And he's just added a new feature/plugin called "SiteShot" that adds a "Browser Shots-type" image that makes this plugin more useful than I could ever have dreamed!
Not only is the plugin easy to use, anytime I've had a question or a feature that I've been interested in, the support is unbelievable! And Steven is constantly adding new features to his plugins. In fact, I am getting ready to purchase another plugin that fills another need. Great stuff and great support!
Update: The plugin is now mobile responsive! AMAZING and FABULOUS!
