Hey everyone!

Thank you so much for all your responses so far (especially you two, Rob an=
d Sean - so much info!).

Well - Sony must have done something right because just about everyone is r=
ecommending the Sony PCM-M10.  I will probably just order one tomorrow.

So now I'm stuck selecting a pair of microphones.  I am taking all of your =
suggestions into account and I think I have a lot more learning to do.

I like the Sound Professionals suggestion and it just might be what I'm loo=
king for ... for now.  Apparently Sony only provides ~3v of Plug-In Power -=
 should I get one of those little 9v battery supplies for whatever micropho=
ne I buy?

I'm concerned about a car or bus completely overwhelming my microphones in =
somewhat loud street environments.  From what I've learned, that situation =
is helped by some kind of "pad" or attenuator cable and/or a battery supply=
 giving more power to the microphones to avoid clipping.  Am I going in the=
 right direction here?

Rob - thank you for all your hard work and your verbosity.  However, I'm no=
t sure I can really justify buying Telinga's offerings at the moment.

At the same time, I wonder if there is some nice place in between the Sound=
 Professionals' ~US$80 offering and Telinga's ~US$750+ offering!  Does anyo=
ne have anything favorable to say about Core Audio's ~US$250 offering?  How=
 about products from Microphone Madness?:
http://microphonemadness.com/products/mmhlsomsenmi.htm
I haven't read any real reviews of their products.

I have heard nothing but good stuff about Sonic Studios' products but jeeee=
eeeez ... I can't afford those either.

So here's my point - maybe Sound Professionals' US$80 products are good, bu=
t if I can get anything substantially better for ~US250 I'll totally do it.

And again - folks - thank you for sharing your advice and expertise.  I'm s=
ure newbies post in here for this kind of advice all the time and yet you h=
ave been so patient with me.  I can't wait to make some recordings for you =
all to listen to.

-Christian

p.s.  Can anyone point me to a good primer on learning what you guys are ta=
lking about in terms of dB's?  I'm trying to learn how to distinguish betwe=
en microphones and I can't decipher all the values.  I think I have a prett=
y good idea about what a noise floor is and what self-noise is ... but afte=
r that I don't really know what to look for.

p.p.s.  It's ~3am - time for bed
