Been using digRotate for years now. Support is excellent.
Great events module. Best out there. Payment integration was key to our success!
Chad and his team at Data Springs continues to out do themselves and provide the best modules on the market hands down. From Dynamic Forms to Dynamic Modules to Dynamic Registration, they keep getting better. Integration with Dynamic Login to Facebook is paramount with todays socially connected audiences. I can't wait to see what Data Springs brings next. Support in the forums and directly is also amazing.
Netism Map Extreme is amazing. The integration to both Google and Bing allows for excellent customization depending on your requirements. The ability to connect to external data sources allows us to control our data through other sources while offering a seamless mapping solution for our visitors. Support is unbelievable and quick. Thanks!
