With Libgen I've realized that I can buy a $400-$800 e-ink device with a 10-13 screen and save thousands of dollars, pays for it's self in one semester. I think they have color screens and/or laptops that have a secondary e-ink thingey now. If you don't need to read technical PDFs and/or 10+ hours of screen time don't give you a screaming headache, save money and use whatever you're using to read this. If you just need the text you can go with a cheap kobo, pocketbook, low-end boox, etc. I'd skip the kindle, heard they can be fiddly to side-load and I'd prefer such a device to be strictly offline.
