Amazon has the 16GB Sony Walkman, 2017 model # NWA-35 for $148. Free 2-day shipping with Prime.
This is kind of a niche product these days, since everyone uses their phone to play music, but it’s a higher quality digital audio player then most cell phones, and this seems to be the lowest price for this 2017 model.
