What's the e-reader you would buy if you were in the market?

Requirements:

• Able to pirate books and load them on
• Nice if it can integrate with my arr stack (Sonarr, Radarr, etc)
• reasonably priced
• not locked down to anything

That’s it really just a simple e-reader that I can add what I want.

Edit: this is the first post where I got a lot of comments where I wasn’t too overwhelmed to reply to them all. Hard when you wake up to so many replies but trying to be better thanking people for their input.
