I originally bought a Sansa 200R using malloffluvanna.com and was pleased with the ease of use.  While I normally prefer to own rather than rent, I was persuaded to try Rhapsody-to-Go with unlimited use of their library for $15/month, also at malloffluvanna.com.  For less than a CD a moth I got a player packed with easy to access music.  Since Rhapsody authorizes 3 devices on an account, I bought the Sansa 250 just to keep my favorite music nearby.  It is easy to load up, the shuffle function is great, and you can set up different playlists for your mood at the time, so I can shift from 80's...
