First off, thanks for the feedback.
Minimum is two tracks, never mix on set, SD card is fine, time code would be nice.
Wallet is getting shallow after mics, I would love a unit that pays for itself but this is really a hobby so not likley.
In the end I need to upgrade the equipment I’m currently working with due to noise and low levels.
All in one package I’ve been seriosly considering the Fostex FR2-LE. It sounds like I could add the mixer at a later stage if I need to.
