Query: Sony Sports Groove Walkman

It's getting more and more difficult to find personal cassette players today, but more and more people are listening to audiobook cassettes. Well this is the personal cassette player you need. It has every thing you'd want. I especially like the auto-reverse component. The only thing I'd change is the headset. I changed mine out for ear-buds.
