MP3 CD players have been around for a while now. A few years ago, they were an affordable answer to expensive, low-capacity flash players and even more pricey (and clunky) hard drive players. You could burn as many 700MB CDs full of MP3s as you wanted and listen to them on a portable CD player. It's still the most economical method of listening to MP3s on the road, although the players are bulky by today's MP3 standards. Check out iRiver's $130 SlimX 450 or better yet, try a Sony or a Panasonic MP3 CD model--they both retail for less than $60.
