I've used Graphics Server, too. The MSGraph Control is actually a Pinnacle product licensed to Microsoft.

FWIW, my opinion: If you are experimenting, MSGraph is fine to learn with. If you are working on a commercial application, or need flexibility, I think you'll find Graphics Server is worth the $235 it costs. In the same package with the OCX is an FLL version, which I found to be faster than using the OCX. You can distribute your apps with Graphics Server royality-free.
