Many MP3 players come with a voice recording capability, and these usually
hold much more for a comparable price than specialized voice recorders.

I've been using a MPIO FY200: http://www.mpio.de/site_eng/fp_FY200_02.html
but then switched to an Olympus DS2200:

Not sure it is really better though, and thinking of switching back.
MPIO is very compact, records more bits/sec, but is not robust and has
terrible instructions and support.  The Olympus lasts twice as long before
replacing batteries, and has a stereo mike, but that busted after a few 
months.
