Perhaps a different approach would better meet your needs.
You might consider the Ectaco jetBook Lite.
http://www.ectaco.com/ectaco-jetbook-lite/
It is often available for under $100.
The main feature that you might find useful, is that it is powered be 4ea AA Batteries.
It runs for 25 - 30 Hours of actual reading time on a charged set of common NiMH AA
rechargeable batteries. There are many charging options including solar charging.
The use of user replaceable, offline chargeable batteries has a number of advantages.
The most often mentioned being the fact that you can replace a set of batteries very
easily and quickly, and get right back to readding. An internal battery will require finding
an outlet for the devices proprietary charger and a four hour period for it to charge,
before you can use the device. If you are on the go you can replace a set of batteries
and continue reading, then when you reach your destination/hotel you can recharge
the set that ran out, while using the set you replaced them with. It is unlikely that you
will spend 30 hours reading before the set in the charger is recharged and ready to go.
The jetBook Lite (JBL) uses a 5" reflective (no backlight) TFT black&white LCD display
that can be read outdoors in sunlight (a little shade is advised though). Some people
prefer this display over e-ink (another non-backlit display). The lack of a backlight is
a major factor in the battery life of these kind of devices.
It is very "sideloading" friendly, and since it has no WiFi or other radio device to drain
the battery, that is a good thing.
It supports three DRM scams and a large number of ebook file formats, one of the most
extensive list of any dedicated ereader. It has ADE support, so it can handle the DRM
used by most US Libraries. (Don't know what Canada uses.)
It is a pocketable 5" ereader and you can also fit a set of four charged extra batteries in
the same pocket. If you are out and about when the 25 -30 hours reading time runs out,
on the set in your JBL, you have another 25-30 hours with those extra batteries. If that
were to not be enough for some reason, you can buy AA batteries most anyplace in the
world.
Luck;
