Amazon Kindle Fire 7" Gen 5 39.99. I picked up another one of these at this price its back on sale again, these were a few hundred just two years ago this model will take a sd card and is wifi. I use these for books and storage of helpful information I have solar portables that charge it so rather then carry a crap load of tech books I keep them on here, you can also put tech videos and instructions, its a good prepper resource with SD you can fit a ton of material. I think the sale is two weeks ? You can get more memory if you want, I found the sd care works better then paying for added memory.
