Which Model is right for me (and other questions)?

That's what I figured. Thanks.

Concerned about the Model's reliability as an audio interface, however. Have read mixed things.

Suppose I could also add a Mackie Big Knob or similar box and run both my Motu and the Tascam through it into my desk monitors, switching between them as needed, if I'm concerned about using the Tascam as a sound card for general use, gaming, etc.
