How many, and how cheap? We sell a number of bare-board MP3 players that are designed for hackability: http://www.sparkfun.com/products/8819 http://www.sparkfun.com/products/9943 http://www.sparkfun.com/products/10608 http://www.sparkfun.com/products/10628 We also sell the bare ICs. All the design files are available so you can create your own design based on one of ours if that's how you want to go. Mike H.
