Or anywhere, really. This statement: "Grab a reMarkable or Kobo and get hacking" isn't realistic to me. I don't run out and buy current products that cost $300 to "get hacking."
Hacking on a panel scrounged from a discontinued product, or a bare one, sure. But when you're spending multiple hundreds of dollars for a new part, I don't consider that the hacker realm.
Nothing against the author; I've been looking at E-ink for a long time and this page is inspiring. But in the end, the cost turns me away yet again. Also the pitiful refresh rates I've seen...
Look for a second hand device then? I don't know what the situation is like for Remarkable, but Kobo has been around for over a decade and used ones are floating around the second hand market. (The Kobo Touch was introduced over a decade ago and is hackable.) If you're willing to scavange just the screen, there are even more options since you don't have to worry about the device itself being locked down. The drawback with scavenging screens is you have to figure out how to interface to the screen, which is quite the barrier to entry.
