Budget Friendly with SD Storage with other caveats.
I'm looking to get a e-reader specifically because I've heard of Amazon and their nefarious ways. I primarily read through the Kindle app, I do have a Oasis 10 that was very generously given to me, however it is very slow and I very much would like to get any reader that has an SD card slot so I can expand the storage on. I plan on putting my entire library on multiple SD cards. Some of the things that I have listed down below I'm not sure if it's capable on e-readers, outside of the Oasis I mentioned above I've never had an ereader so please excuse me for being ignorant on the subject.
#1 budget friendly Under $300 if possible.
Color a reader would be nice but not needed.
I would love to be able to download Hoopla, Libby, Bookshelf Kindle for KU and Audible apps.
Connect Bluetooth Earbuds for Audiobooks.
Ability to use my Page Turner.
I read and plan on downloading fanfiction so I would like for it to be able to open different types of files.
