Bigger E Ink panels?

I am interested in a bigger than 13.3in eink panel.

Has anyone used one of these? Which size/model? If so, how did u control it?

The next available size is 25.5in on most offers i see, but something in between would work for me too.

I don’t need color, but it would be nice.

Are there models around targeting the maker market?

@ Team Pimoroni: Did u ever consider to offer A bigger screen? What goes against it? Price? Demand? Technical issues?
