Hi Chris,
You could for instance use one of the following electret microphones that b=
oth cost 580$:

http://www.avisoft.com/usg/knowlesspm.htm
Higher sensitivity (lower self-noise floor) and a flatter frequency respons=
e is provided by the more expensive ($1600) condenser microphone model CM16=
/CMPA P48:

On request, the lower frequency limit of these microphones can be reduced t=
o 2 kHz.
These are phantom-powered microphones that require a recorder that supplies=
48V phantom power. A suited model would be the Tascam DR-680. Unfortunatel=
y, the larger brother of the Korg MR-2 (which does not provide phantom powe=
r), the Korg MR1000 is quite noisy at ultrasonic frequencies and therefore =
not suited for your application.
