Need help picking a portable audo player (MP3, WMA, AAC file support)

[ChrisOjeda]

I am feeling a bit overwhelmed looking for the right player. If you know of a player that meets my requirements please let me know what manufacture and model.

Requirements:
Support AAC and WMA (MP3 optional)
Storage medium is memory (don't want one with a Hard Drive or one that plays CDs because this is for the gym so no moving parts is good)
Supports either USB or Firewire

Well that's it....I just need some tunes while I try to lose some weight at the gym...

One more thing...know of any good sites that do reviews?


UPDATE---->
I should mention why AAC is important and MP3 is not...basically AAC stores higher quality per same bit rate and takes up less space...This is a known fact....or you can read about it at various hardware sites like Toms Hardware Guide


UPDATE---->
Yahoo had a great search tool that let's you pick file formats as a fitler among other things.... Portable Audio Player Search Tool

Wow thats interesting, I've never heard of AAC. Sounds very interesting.
I tried looking up portable players with no moving parts that support AAC and all I come up with are a bunch of CD players. I guess we'll have to wait a few months for a portable non cd AAC player to hit the market, I want one now =P
