CNET has taken a look at the Audio Fusion DMP digital audio player from FReestyle which features 512MB storage capacity, here's a small snip from their full test report :

Music can be a great motivator when you're working out; just go into any gym and you're sure to see tons of people sweatin' to the oldies with MP3 players. However, for water babies, this capability has been largely limited because these devices aren't usually waterproof. There are a couple of companies that have come up with creative solutions to the problem, such as Finis's SwiMP3 and H20 Audio's SV iMini, but these waterproof players and housing apparatuses haven't met with much success. Now, the Freestyle Audio Fusion DMP Waterproof MP3 Player is giving it a go, setting its sights on surfers, wakeboarders, snowboarders, and swimmers. The pricey flash-based player is submersible in up to 10 feet of water and is available in 256MB ($199.95) and 512MB ($249.95) versions. All in all, the Fusion DMP delivers as advertised but needs some work in the design department..
