I'm using BT Google Maps Free version for my Joomla site. It's awesome. Now the provider has released BT Google Maps Pro which is premium version of that free product. It offers many great features ("one-click importing thousands of places by importing/exporting data function, map style customization, enabled/disabled various fields on map function, uniting places by marker clustering, and route direction") which I'm interested in. They sounds fanstatic. I think many people need a Google map for their site. I'll buy it and share with you my feedbacks. : ). Hope this helps!
