Do you have a chance to test Kobo Aura HD in a shop? It's not too bad, even (as seen on the web) for PDF. I was testing it just today. But so far my KK is working. Recently it majorly froze though and I was torn crossing fingers as I didn't know to keep them crossed for it to die (and I can have a new gadget) or it revives. It survived.
And you can check Cybook Odyssey HD frontlight from talia.de (or thalia, can't remember)
Edit: great minds think alike
