I seriously do not like people saying "it's on AliExpress". I'm sure it is, but the problem is quality control so a specific link is greatly helpful.

I'm afraid I can't really vouch for any specific one, it's been years since I've messed around with one and suppliers change their stock constantly.

Yeah, there's a ton of e-ink displays, most of them do not come with the controller or are replacement for kindle (how to drive those?) or are tiny.
