This one looks weird but actually works and sounds great!
The very best bang per buck I've found for this situation is coupling a Denecke AD-20 with a Nomad Jukebox3 - the Nomad has mini digital in and can record at 44.1khz in standard 16bit wav - has a great long battery life - easy menu - fast firewire and usb2 transfers - big hd - minimal cost - especially when purchased used. The Denecke is a great portable stereo A/D & pre that will work fine on any non phantom mic - if you need phantom you can rig it seperately. If you find both of these used - get em - you wont be sorry. You just need to make sure to make a sturdy portable case for the 2.
