First post! Sorry tapers that we're moving away from taper-talk on this thread!
I am a reporter. What you're describing is the holy grail. I haven't found it yet. I got a Fostex FR2 LE. Good deck, although the engineers for my old show called it "Le Brick." I guess the decision for you is what you'll would be willing to sacrifice. The new MT sounds good, aside from their stupid insistence on a proprietary battery which for reporting feels like a deal-breaker. One consideration to note, ALL of the flash decks I've used have trouble giving enough gain to dynamic mics. My FR2 LE really sounds great, but with my high-output version of an RE50, I have a hard time peaking past -20 dB or so. Fortunately, the preamps are clean enough that you can boost safely later but it's still a pain. I've actually found that Minidisc decks, for whatever their problems, work well with dynamic mics. You might consider getting her a Hi-MD, despite the mini input, and buying up a big stash of Hi-MDs in case Sony stops producing them soon.
Good luck,
Brett
