Could anyone recommend a decent MP3 player for kids/teenagers? I would like to get one for each of my kids (middle school & high school) for Christmas but I don't want to spend a lot of money. Sadly, there is a good chance that they will lose it or it will be stolen.

I bought a little 128 mb one from Ebay but it's pretty flimsy. I just don't have much experience with them and wondered if anyone else has. Thanks.
