I'll probably buy the 103 because I tend to replace my players often, and currently have the 93. Any thing else would seem like a downgrade.

The 83s have the ability to play ripped CD ISO (?) files, if they have an older firmware version that allows it. That's what is driving their cost up. Not so sure about what is floating the price of the other players.
