TL;DR - sorry everyone, I just can't swing the ~$13k USD for a PnP right now.
The cost of the TVM920 is equivalent to 6 months' base expenses, so it's a big deal for me. With no consulting clients lined up yet, I decided it is better to play it safe and conserve startup cash. Once I am running and in the black I can revisit.
So, in order to have *something* to work with ASAP, and minimize the cash outlay, I've decided to do an OpenBuilds machine. BOM is only about $1k including vision. I'll open a new thread on that topic.
