I use a Rio Chiba 256(mb). I added another 256mb SD card to it. I think I can get about 100 songs on it. It will run about 17 hours on a single AAA battery. Very small. Fits great in my jacket pocket. I bought it last year for about $140, but it's down to about $108 on Amazon.com now. I also bought Sony earbud headphones which sound great and seal out a lot of noise.
