My old one got squished in moving. It was a Kobo Klara I got as a gift. Before, I had a refurbished kindle paperwhite 7th gen that I liked the UI of much more but didn’t like having an Amazon product.
Wondering what is out there now.
My main desiderata is that it has warm backlighting and is small. Would also like better .pdf reading than the Kobo that was basically non-doable.
Another one I’ve seen out there that seems decent is PocketBook, but I’ve never bought one. You might be able to find a used one for $100.
