2052 just purchased 6
Amazon Fire tablets.
They're pretty good tablets for only $50, plus you can buy 5 get one free. It's like Amazon is catering to people scouting 6 robots! The official cases are buy 4 get one free.
Of course, there are two caveats- they come with ads and they aren't true Android. However, the ads are relatively easy to disable, and scouting apps should work just as well on FireOS as "real" Android.
I'd definitely recommend at least considering them.
