An alternative to the iPod for portable field recording is the Archos Gmini
120.  It will accept an external input (line level) with a fixed sample
rate of 44.1 kHz in WAV format.  Alternatively, you can use the built-in
microphones that record at a sample rate of 22.05 kHz (like the iPod, this is
fine for voice).  The device also records in MP3 format, but a linear format
like WAV is best for field recordings.  Because the external input is
line-level only, you'll most likely need a preamplifier for your microphone.

Good luck,
