A Kindle seemed like an unnecessary luxury item until I was gifted one a few years ago. Now I couldn't live without it. I do so much more reading thanks to easy access public domain and library ebooks, and I vastly prefer the Kindle reading experience to paper books.

A used older model Paperwhite is under $100.....though I say go for it and get the newest model new, if you hate it then Amazon has a generous return policy. Be sure to get a case (people on r/Kindle say the kids bundle is the best value).
