Query: POS! Don't buy!

Well, I researched MP3 players online and felt that this one was the best comprimise between price, weight, and storage capacity. I liked the set up and ease of uploading songs too.The problems! It stopped working on day 3 of using it! It was powering off in the middle of songs or when a button (volume, menu, etc.) was pushed. The online support said to fix this: download the latest firmware (ok, did that), and if it still 'locks up', reset the player by turning it off, taking the battery out, putting the battery back in, and turnin it back on! ARE YOU KIDDING ME! Real technical solution. Well I had to do that every time I wanted to skip songs or change volume. Then it just quit powering on all together!I plan on getting another brand of MP3 player around 128MB built in with expandability or a Mini Disk player. Taking it back to Best Buy! My single experience with Rio has been bad, and for that price, it is not acceptable, so I am changing brands!
