Actually, I've gotten PCB's (about 6in by 6in, double-sided w/ silkscreening) made for about 33 bucks under academic manufactuing pricing, which I think a lot of american pcb companies do. If you're really interested in doing this project, I'd google for pcb vendors and ask them about their pricing. If it still seems too costly, you might want to think about replicating the mp3 player PCB design on one large board. Then you can break the board up and try to sell some additional mp3 players to your friends or have an altoid-player building party!
