Hi- I just recently bought a used Sony MZ-R700 MD recorder. I'd like to use it for recording wildlife sounds/birds/etc. outdoors... Can anyone recommend a good microphone for this that is economical? I read a thread where the Visivox binaural mic w/ pre-amp was recommended, but then read another thread where that's not a good choice because the MZ-R700 doesn't have 'low frequency sensitivity' or something... Anyways, I'm a newbie and would appreciate any advice. Thx. -bartidge
