Amazon Kindle 4th generation (not the backlit, touchscreen one, rather the old version). You can buy a used one for about $25 - https://www.ebay.com/itm/134613535149. I've had about 4 of them, they last forever but you will ding the screen up if you drop something hard like keys on the screen. I don't connect the wifi, I just transfer books via cable (easy with Calibre). With no connection, it's like a book and not a distraction device. And practically speaking you really can't browse the web even if you're connected, it's so painfully slow and awkward, without a touch screen
