We recently got my son an e-reader because I got tired of carting books around and my son was getting through books so quickly my hubby was complaining about our book expenses (don’t have good libraries here either). If you’ve got an e-reader and are looking for classics for kids, there is an excellent collection of 225 books for $49.95 (you can choose Kindle format or ePub):

If you’re looking for an e-reader, you can check out our experiences with the Kobo Touch and Sony PRS-T2 here:

I know most people get a kindle but kindle doesn’t sell books to this part of the world 
and most of my collection is in ePub so I wanted a e-reader that supported the format I had, which Kindle doesn’t.
