Sony Network Walkman NW-E107 - Digital player - flash 1 GB - WMA, MP3
I have loved the unit itself.  I had a minor issue in which I had to send it off for warranty work a few months after the purchase.  It has worked great & I have enjoyed the quality of the MP3 player itself.  The problem is that after less than 2 years of it being out, it is no longer possible to find the armband to carry it in.  I have looked all over the Sony website & called their Sales department.  It is not available anywhere.  I have used the Google search engine looking for any place that might sell
