Need some $200 recorder advice, please.

["ndbdxr" ndbdxr]

Dear Folks,

Having previously owned a Zoom H2, I am getting ready to purchase a new por=
table digital recorder (in a week or 2). My wildlife recording is focused p=
rimarily on singing insects, followed by birds, etc.

(As per my budget) The 3 recorders I've narrowed it down to are:

A.) M-Audio MicroTrack II
B.) Olympus LS-10
C.) Tascam DR-1

(You can currently find each of these on e-bay right now, for ~ $200)

Just to make it easier - My question focuses on using the built-in mics onl=
y. In the case of the M-Audio, the provided "T Mic assembly"

Which of these is the best performing field recorder?

As for external mics: I only have a very cheap Mono shotgun mic, and a few =
home-brew mics, etc. that I currently experiment with...

Thanks very much!

Best regards,

Al
