I'm selling my PRS-500 because I'm going to get the 505 soon. It's in near perfect condition and includes all of the packaging and cables. I'll take $190 plus shipping for it. I purchased it last June.

I would prefer to sell it within the U.S., but we'll see if other arrangements could be made.
I now have an ebay listing for the reader:
