I have a US wireless 2nd generation kindle for sale, 6 inch screen + leather case (Kindle retails for $259+$29.99 for leather case), selling for $270 OBO.
It's fantastic - and amazing for reading books in bright light (the screen doesn't reflect).

I bought it for my around the world trip, but my boyfriend and I have decided to share his instead to avoid carrying two devices.  So mine is available for sale when we're passing through Laos (currently in Vietnam).  I've only had it for 1.5 months and it is in perfect condition - of course, available to be looked at!

here's the amazon link:
