I have a Panasonic RQ-J20x walkman. It's in great shape and has the case and strap. The only problem is that I can't seem to figure out why it doesn't play. when I hit play, the wheel makes about 2-3 turns and then stops like I cut off the power but the Ops light is still bright. I looked inside and the belt is just fine so I'm kinda stuck. I don't want to dig into it too much because it has a very thin delicate circuit board in it, and from what I hear it's a very rare walkman so I really don't want to spoil it.
