Query: 20 Gig Paper Weight

I bought this particular MP3 player for several reasons. One was that I was going on deployments and was tired of carrying books of CDs that could get scratched, lost, or stolen. The 20 gig HD was perfect. The FM radio was an added bonus. And for a while, I loved this thing.However, when I had a problem with the battery, SONICBLUE would return my emails until I sent them 2 more. Then for no reason, the machine got stuck in a loop and would not come on. When I emailed SONICBLUE 3 times about this, they didn't even respond.I downloaded firmware, software, drivers and everything from the web site with no succes. It's been about 2 weeks since my last email and still no reponce. DONT BUY THIS PAPERWEIGHT. IT WILL CAUSE YOU GREAT FRUSTRATION. If nothing else I have said has convinced you, look at this. This unit first went on the market at almost $$$. Now, you can get for almost half that.
