@Jo @Canageek@cybre.space Yeah, this one is definitely not good for reading longer text off of. They have larger displays, but they're a power of 2 increase in price, with the >9 inch ones running $200 or so (ie, more expensive than buying a Kindle and deconstructing it).
You also have to do the text wrap and/or conversion to BMP yourself, though I'd bet some output format from Calibre could work.

@Jo @Canageek@cybre.space Looks like the 7.5 inch one is ~$75, though, so that could be a starting point.
Also, if you build such a thing, make sure to select the two-color models. The tri-color ones take forever to refresh the screen (the refresh rate on these is also pretty long, though apparently there are others that are faster).
