+1 to Kobo as well, although I’m admittedly unfamiliar with the pirate apps (arr).

no issues downloading books and adding/editing my library with calibre and you can connect it to your library card to rent ebooks if you’re feeling frisky.

or you can bypass the login steps and change out the firmware and add games and other utilities. it’s as customizable or not as you want.

lots of refurbished options through rakuten and ebay
