These are listed as 'Discontinued' and/or 'Sold Out' everywhere online. Fun fact: the distance from the end of the housing to that little fork thingy that connects to the cable on the hub is fairly critical. To make sure this was correct, SRAM sold the shifter+cable+little fork thingy only as pre-built assemblies aaaaaaaand never published the distance to set the little fork thingy from the end of the cable housing. But, and it's a big but, they created a tool to set this distance:



Unfortunately, no living person has ever seen one of these tools.


I imagine two SRAM executives sitting in an office. One asks, "Our IGHs were technically superior to Shimano and Sturmey. Why didn't OEMs order them? Why didn't consumers like them?" The other executive shakes his head and shrugs.
