I've been thinking about this for a long time and thought I'd get some opinions from you guys.

The Plan:

Portable Part: Assuming I can take lines from the bands mixer.

Alesis HD24
Mackie 1604 Mixer (or bigger)
PatchBay (easy connections)
4 603s for choirs without mixers
couple of 57s, 58s just in case.
couple/three RNCs

I'm looking for the easiest ways to make 1 or 2-track field recordings, from outdoor sounds to a quick set-up for the occassional jam. I've been looking at the Tascam 564 (perfect, except for the early version of ATRAC compression and no phantom power, and I don't necessarily need all 4 ins, or the editing abilities), and that got me thinking about using one of the little player/recorders.
