Saved and liberated the books I "bought" at Amazon for my Kindle. Amazon will stop offering the "Download & transfer via USB" option, so I have downloaded all 210 books. After downloading, I hunt them through Calibre and a certain plugin to remove the DRM stuff, convert the books to EPUB format so I have my private backup and can put them on a new ebook reader that is more open than the Amazon walled garden. And in future I will buy my eBooks someplace else. #ByeAmazon
So yes, I am in the market for a new ebook-reader. Nothing special, should be similar to the Kindle Paperwhite (1st gen) I have been using over many years. Backlight is a must. High resolution a plus. Long battery life (weeks) should be obvious. So if you know about a good and not so expensive device, please share!

Very happy with my #remarkable.
Maybe take a look at the new version
https://remarkable.com/store/remarkable-paper/pro

Supports pdf and epub, without DRM. For the pro version colors and backlight was added.

Some features require cloud access, which comes with a small monthly fee, but a lot of people dont want that. Additionally the cloud is hosted in the US, at least I think so.
I use it only via USB.
If you dont mind a little tinkering, selfhosted is an option:
