Here's the most compact player by Sony, the WM-20. I got the player about 2 months ago, and all it needed was a new belt and some elbow grease. To compare it to my other player, (the WM-22 by Sony), i'd say that while it looks more serious and less fun, the sound quality is just oh-so better thanks to Dolby NR. Here's a close-up picture of the transport controls, And here's another one with the side visible. If you're wondering where the audio jack is, it's nested behind the front door, just under the battery text, see on the picture underneath. Thanks for reading!
