I've got a Sony PRS505 Reader (which you can currently buy (http://www.waterstones.com/waterstonesweb/products/sony+prs505+6e2809d+ereader+28manufacturer+refurbished+model29/6337796/) secondhand from Waterstones for £60) and I love it. The display is easy to read and with a decent case (not the Sony one; I have a Tuff-Luv one) it's pretty close to reading a proper book. Mine has been all over Europe with me; the charge lasts forever. And you can put on pretty much what you like.
