I normally use a Kobo with Calibre to read eBooks.
But every once in a while, an eBook only exists in PDF and the PDF -> Kobo ePub conversion doesn't usually go well.
I have an old Nexus 7 tablet from 2013 that I have used for that purpose, but the backlit LCD screen is too bright even at lower brightness to comfortably read after dark.
I know of the ReMarkable, but they're very expensive and it's hard to justify the cost as most of my reading is ePub.
Is there a good alternative in terms of price, availability outside the US, and functionality that I have overlooked for that purpose?
