Hi Arwen,
I've been following this conversation and suddenly clicked with what I thin=
k you could solve your cost V quality problem with.
I bought a pair of these:=20=09
Shure Microflex Wired Boundary Microphone - MX391 ( on ebay )
http://www.ebay.co.uk/itm/130614482589?ssPageName=3DSTRK:MEWAX:IT&_trksid=
=3Dp3984.m1438.l2649
after reading a conversation here about them.
They are very quiet microphones, by comparison with anything near this pric=
e. They are omni mics and sound great. The low frequencies are pretty loud =
so a bass roll off at the input stage is a good idea. I don't know anything=
about your recorder so I'll let someone else comment.
These mics are a one-off offer, so I'd suggest you make up your mind pretty=
quick. There are post here in the archive that discuss them, from about 6 =
months ago or so.
I got mine wired up to a stereo 3.5mm plug in very quick time, and I'm chuf=
fed to bits with them, for the money.
Good luck with all the decisions,
norman.

a lot of the mics *appear* to have relatively low sensitivity (to the ME66=
, for example), and when all's said and done high self noise too. The Rode =
Videomic Oryoki suggests is only 15 mV/Pa... and has a self noise figure of=
20 dB(A). It might be my best bet for getting started though.
