We were looking for a GoogleMaps plugin for one of our client projects. The previous basic plugin worked ok, with the exception of lacking the option to import all the placemarks from a CSV file, which was crucial to have.
After coming across this plugin, the import issue was quickly resolved (the geocoding was done through http://www.gpsvisualizer.com/). The import alone is worth getting the Pro version.
There was still some small customization needed, which we got done by the plugin developer, who'd implemented some custom code changes for us to get the new requested feature to work.
Thanks so much, Nick!
