I tested a few directory plugins, including some premium ones from Theme Forest, and this is by far the best.
The admin area is simple and straight forward, theming it as easy as you would expect but most impressive is the support.
We bought the premium Google Maps plugin and found a few problems with theme compatibility (we were using Dante, a very complex/feature rich theme, conflicts abound). I let the devs know and they dug right in. In a few days they sent a RC of the plugin that addressed google map api problems directly. I installed the update and it worked like a charm.
Good coding is one thing, but to really stand out and be exceptional the test is support, and the team that builds this plugin excels like few others I've seen.
They're the tops. Install this plugin!
