I bought the JetBook Lite a few days ago and started loading comics to it and I got to say "wow" it has great quality (after being converted from cbr to pdf with calibre). The zoom function is useful for the hard to read parts and the loading speed is fast (a few seconds to load a comic one second at most after to turn the page but most of the time its instant). For a budget E-Book reader this does the job. No back light and no internet but for the price it's fine. The only minor problem I had was the default conversion of CBR to EPUB, i was getting a "not enough memory" Error, PDF is a little bigger 5mb - 10mb but does the job. Here are a few pictures of the JetBook Lite VS Laptop CBR Reader.
I have also made a video to show it in action..
