I hear ya on the commercially available hoods not looking right. This is a "custom" hood: The vertical pipe is standard stovepipe from Home Depot, the white flange is something I found at Habitat for Humanity (not sure what it is originally from; it conveniently had a hole that matched the stovepipe), and the fan is an old skool looking bathroom vent.

I adore this kitchen its so sweet, warm and welcoming,
