Rode has a reputation as a maker of good quality microphones at a
reasonable price. I've not used one myself, but I recall fairly
afirmative reviews of earlier models in the now sadly defunct Studio
Sound. And there's a clue there, Syd. I doubt that too many have
been road tested (pardon the pun). Of course, that should be
subtropical forest tested. Others on this list have praised
Sennheiser mics for their reliabilty in such conditions, and I know
from experience that Sennheisers have worked where other mics have
failed. So I'd only buy the Rode if I could try it thoroughly first,
and in the southern hemisphere, I'd wait until midsummer before
testing.
Good luck with the lyrebird. I wouldn't mind some of that myself.
I'm on the trail of one in Kinglake National Park, not far northeast
of outer suburban Melbourne.
