What plan comes after reseller?

I want to upgrade beyond Diamond reseller. What plan do I choose?

If you need more bandwidth or disk space than our highest plan offers, please purchase a second reseller plan to accommodate your needs, or upgrade to a dedicated server.

(The main point of upgrading to a VPS from a shared or reseller account would be for flexibility in software installations, Apache configurations, and other custom software (ventrilo, ffmpeg, etc). A VPS also provides more freedom to send emails and stream media. A VPS is not a solution to an overly resource-intensive account.)
