Yes, the zoomH2 works well for directional stereo (but not true binaural without the mics - you need a head in the way for true binaural recordings otherwise it's just good stereo)
The mics I bought are powered by the Zoom and pick things up well enough for me.
The Zoom also works well with the Radio Shack induction mic but I use a mono-stereo adapter (I never do trust that the mono plug will span both points in the socket and do joint stereo) with it. I know a mono jack should be fine and will record on both channels but I had one once that didn't.
I'm not sitting for another hour to re-record or fiddling about copying channels when I get home.
I do find that the Zoom (using the two front mics) is quite a good directional mic as well if you can get a good line on a speaker that's not too far away.
Can't post the ones that came out best (commercial stuff) but here's Buzz Lightyear.
Just popped the mics in and switched on and let it run (set the level, of course).
I did try not to turn my head during the ride! The mics may have dropped out a couple of times, not sure (must listen again).http://www.mediafire.com/?1lwro087a8xvnsl
The Zoom (on high gain) also picked up a passable area loop of Toad Hall from a speaker I had to bend down and put my ear to in an effort to hear if it was working (it's the only speaker with full access and no CMs and also well out of sight from most people - it's down the side of the -unused this year - festival stage next door to the restaurant.
Unfortunately, can't post - commercial tracks.
It's a good little recorder.
