No, I don't mean concerts, I actually do mean recording stuff "in the field" -- I heard a really cool sound last night, and I didn't think of my iPhone (duh!), but even if I did, I want to get serious about this.  I want to have access to a quality portable digital recorder at all times (I.E. if not actually with me, then with me as much as my iPod is). 
 
So, I realize this is not the best place to ask, so the question is mostly -- where should I go to ask this?  Harmony Central?  Any place else?  I can't remember the music makers and producers forum that I used to frequent -- gear-freaks or something like that? 
 
Here are my choices so far, that I can figure: 
 
Tascam DR-1 or DR-07 
Alesis ProTrack (requires iPod) 
Zoom H4 
Edirol R-09 
Olympus LS-10 
 
Any others I should be looking at?  Would like Hi-Res (either DSD or high bit-rate PCM).
