I have a month (a little over month) old black PRS 650 which I barely use. I am selling it for $230 with first class shipping with tracking in US only. Outside US, shipping will be extra. I have sold PRS 505 sometime back as well on this forum with good rating from buyer. It comes with original box and accessories. PM if you want to see the pics.
