As far as I’ve seen/read they don’t really do sales ever, but sell open box good condition items at a decent discount.
I have the smaller one, and text looks a lot better than my Paperwhite from 2015, but I haven’t spent a lot of time with a newer Kindle for comparison or looked at manga on either. Even with a magnifying glass you can’t see individual pixels on the SNs though so I would think graphical content would look good?
It’s not fully featured but the remarkable series of epaper tablets are supposed to be pretty good and run a Linux fork. The supernote family run a version of Android that’s very stripped down and doesn’t require an account or an Internet connection ever.
