We are using the TatukGIS Developer Kernel for VCL for over ten years now and we are still pleased with it's rich feature set, ease of use, extensibility and performance. All in all it's a fantastic toolkit and a pleasure to work with. And the support is top notch too. So, thank you for that, and keep up the good work!
