Samson has a spin-off called Zoom that makes pretty incredible hi-fi audio recorders. They record to standard SDHC cards, and this one in particular pics up sound very accurately. Problem with “micro recorders” that aren’t pro standard is, the intelligibility of speech at a distance. The mics on the Zooms are studio-grade, and have excellent highs and a very open sound. They are good for band recordings, and excellent for speech.

This one goes for $99 online, however, you could probably google/amazon and find it for cheaper.
