>>931519Any preowned iPad with the Retina screen. It's the same resolution as e-ink (actually slightly higher than Kindle), but it's an actual 60fps colour screen so you can watch videos, read comics, pan/scan around mangos, play games, etc. etc.
iPad 3rd generation is the first one with the good screen. It's less than $130, even retail. It doesn't receive OS updates beyond ones that fix hardware-breaking bugs, but this is not a problem for what you say you want to do with it.
