Condenser mic with 1/8 stereo jack

[9fingers]

My lady/bass player just bought a Zoom H2 & I have a camcorder, both of which can take external mics (condenser I assume) with 1/8" stereo jacks. I am simply not familiar with these mics at all. Any info, links, or recommendations would be appreciated. Gracias!
Edit, did little research- there are such mics, usually with battery power and in stereo. Anyone use an external mic with their camcorder (miniDV in my case)? I would be using it to record live concert sound (mostly my group - a not super loud trio with acoustic guitar, electric guitar, bass & vocals in venues ranging from little rooms up to 500 seats).

Audio-Technica and Sony both make stereo mics w/1/8" outputs.
