Brunel Hand 2.0 from Open Bionics
The Brunel hand from Open Bionics is also discontinued, and links to components point to missing pages. However, it is a well designed hand and worth viewing.

The bill of materials is quite long, especially compared to the Ada Hand. It uses 3 linear actuators instead of Ada Hand’s 5, saving about $150 but losing degrees of freedom.
Open Bionics moved from the Ada Hand, to the Brunel Hand, then received a $1M award that helped them launch the Hero Arm, which you can find at Openbionics.com.
