The Ergotron is amazing quality and slightly cheaper than the Wacom arm, and also has more height adjustability. Food for thought.
For the Flex arm and for the Ergo Stand, you will have all you need in the box. No additional mounts are required.
Could you clarify what gave you this impression from the photos? Perhaps we can make it more clear.
