Equipment options for recording rodent vocalisations

bio-acoustics, I am a recording engineer, familiar with the technical
 terminology. If my query is taking me down a path well-trodden I apologise
 and would be grateful if someone could point me to a previous thread.
 I'm researching proven techniques in the recording of rodent vocalisations -
 initially Norway rats but with options open for further rodent species. I'd
 like to know how folks have gone about this in the past so as not to find
 myself re-inventing the wheel.
 Ideally equipment would be portable - either Windows or Mac-based laptop
 with stable analysis software, a soundcard capable of a sampling rate of
 192 kHz (96 audio), a preferably battery-powered preamp flat to, say, 200 kHz
 and a sufficiently quiet ultrasonic microphone, ideally capable in range
 from the lower hundreds up to 100 kHz.
 Or .a proven stand-alone device with perhaps USB or firewire interfacing for
 a laptop.
 Cost is an issue, though not as over-riding as stability, reliability and
 its ability to function at high temperatures in the field.
 Any advise as to proven hard and software would be gratefully received.
 Many thanks
 David Antony Clark
