What will I be using this unit for:
1) Recording interviews for a research I am doing, in MP3 and a single lapel mic to pick the voice. In that sense the Tascam is more practical because it has its own mics, but I would never be using them for a "quality recording". So I don't mind the MT has none.
2) Recording double-system location sync audio. On that the MT II offers me potentially better capability, as it can record 24/96.
The attractive things in the Tascam were its smaller size and lower price mostly, but I think the MT II has better specs. What I don't know is which is more practical and reliable to use on the field.
Craig, why do you say the line-in would be better on the DR07? The S/N specs are pretty poor. But in fact I would be using this unit with analog sources, always.
