Re: ENG, low light, quick workflow, size, durability...which camera?!

I say a couple of FX7s from ebay for this one. Durable, capable, cheap as all get up, and really all you need for this. They eat light like candy, are small enough to fit in the overhead of the smallest puddle jumpers, and, at their used price point, are dang near disposable. If you got just one as a B camera, you'd have enough left for a 5D with a couple of cool add ons.
