Great device for a great price. I just bought this MP3 Player at buy.com and am very satisfied with it. I really like the interface and it comes with an expansion slot for 2GB micro SD cards. The best thing about it though is that it is compatible with the Rockbox firmware which enables you to customerize the interface, play games, use 8gb cards, play Doom, even run a gameboy emulator. If you get Rockbox remember to use the blue wheel for navigation. Automatic installer utility here. Make sure to go into settings and set USB mode to MSC before install, then back to mtp afterwrds.
