So, what with the mp3 player deaths and all, I'm in the market for a new one. I'm basically looking for something that is 1) reliable and 2) at least 20 GB. The 20-30 GB range is what I'm really looking for. I basically just want something that plays music - doesn't need video or photos or a tuner or whatever else.

Any advice? Ones to avoid would be handy as well.
