The SanDisk Sansa c200 joins the other players in the up-and-coming Sansa brand. The c200 has a 1.4-inch LCD, 2GB of internal storage, and a microSD slot that takes up to 2GB of memory, bringing its total capacity to 4GB. There's also Microsoft PlaysForSure support, along with the obligatory MP3 support, and a 15 hour battery life.
Best of all, the price is only $99, which is pretty good for a player with potentially 4GB of space. You'll have to add on the price of the 2GB microSD card, but you can pick that up for a few bucks online. The c200 will be available in October.
