Sony MZ-R700DPC MiniDisc Walkman with Stick Style Remote
can take a college level beating
I am in college and bought a sony MD player last summer.  I use it all the time, it is great for studying because you can put about five hours of music on it.  I have only had one small problem:  One of the screws on the door fell out.  The problem was small, the Player still functioned, and when I got home sony fixed it for me.  It is also one of the most resillient players I have ever owned, I took it running (no skipping), lifting, and any other place I could.  I droped it a lot but never had a problem, not even a skip.
