Only for reading, easily available in EU, low budget: which e-ink device/distro?

I’m looking for something to read books on, copied over from a local collection (mostly .epub). Networking is not desired, a fast USB connection is. A good battery or exchangeable battery would be nice.

Not too large - maximum DIN A5 for the whole device.

I remember from years ago that some devices were deemed unhackable, some much more suitable to install Linux on.

I’d prefer to buy used, so something that was sold a lot in Europe is preferable.

I will not spend much more than €100.

In other words, some old commercial e-reader that was known for being hackable, I guess.

Please do not recommend the new PineNote, it’s (slightly) too large and way too expensive and I don’t think I need that much computing power.

Thanks in advance.

      Funny, I just did this today. And yes it requires connecting to WiFi and registering the device with Amazon, since the jailbreak exploits a mechanic of the book store. But the new one “adbreak” exploits of mechanic of the advertising delivery system.

      Definitely would not recommend buying one to do this. Kobo is the way (for now).
