If you really want "nothing fancy", you can go with vNotes, it saves the notes in the AMR and WAV formats:
Dollars 5 Complete » vNotes for Blackberry 8800, 8300 and 8100
You should also take a look at VR+
VR+: Record your voice, Email and Share in Facebook, MySpace, Twitter, Blogger.com | Entertainment BlackBerry Software
It costs more, but you can send the voice notes in MP3 to other people or yourself by e-mail. You can send it as an attachment or a link so the recipient can download the file. Or you can just send the file to a remote storage account that is included with the application. It's not a subscription, it's a "lifetime" and unlimited account included with the app. I really like VR+.
