I actually have a little tiny audio/video keychain recorder which is high-def, and has amazing audio clarity. I use that instead. Its cheap (under $12) and it has a low light CCD HD camera built in so I get video with the audio.
It uses a microSD card so that I can save up to 8 gb on the card before I offload. And its small enough to where I can fit -5-6 of them in my pocket for easy access.
