Query: So far so good

I had an MP3 player before that only lasted a few months before not working anymore. From what I read, this is not unusual. This time I bought the Zen Stone 2GB because of the price and lack of negative reviews. The controls don't always work well, sometimes it switches to radio when not trying, or won't turn on or off easily. Also, it seems like the battery needs charging more often than they say. But it was easy to load the songs from RealPlayer, and delete and add songs. I bought a generic charger from Radio Shack so I could charge it from an electric outlet rather than the computer (for trips). It includes a car charger. This for approx. $30, same as Creative's AC charger. I'm hoping this will be the last MP3 player I have to buy for a long time.
