You missed the window on the BS2 mp3 player. A few years ago (2014?), they were selling for silly money in Japan or China. I recall seeing a “sold” ebay listing for ~$1000.00. Alas, I didn’t bother with trying to sell mine because it was slightly damaged, and I have misplaced the dock somewhere (at some point I started using the travel charger exclusively). Lately, I’ve seen one listed for $200, but not if it was triggering any bidding action.
