Just picked up and tested a Zoom H2n. Very inexpensive and small unit. 2 AA batteries and 20 hours of run time. Can be set to either uni or omi directional pickup. XY to one side and mid side to the other (using only two mics for the MS). Ok, it wouldn't stand up to Adele's lyrics but it does an amazing job of picking up ambient sound with very little floor noise. Can be placed on a stand via 1/4 20 threads. The whole unit fits comfortable in the palm of my hand. Has a host of resolutions to include 48K 24bit wav for standard video.
