What is best material to make a vent hood?
I have read the threads on ventilation, but I haven't seen a discussion on what is the best material to use to construct a ventilation hood. I assume a vent hood needs to be made of a noncombustible material, but beyond that, what are the pros and cons.
Cement board: easy to find, can cut with a saw, but will be very heavey to hang.
Sheet metal: difficult to do yourself, I can't find anything on how to build yourself. If I go to a metal fabrication place with a design, what material and what thickness (gauge) should I ask for? (with cost in mind).
what other materials have people used? Aluminum siding? Foil backed insulation board?
Thank-you in advance for any comments.

I've seen pictures of someone using a water trough similar to this-

That trough is very similar to what GlassCraft(?) used for their hood in the kit they sold for a while.

That was my old set up, and I don't have a pic sorry. The one I have now is a frame from a metal shelving unit with plexiglass sides, back and front baffle. It captures fumes very well and my exhaust blower is killer! Here is a pic of it.

Posts numbers 10, 30 and 55 is where you can see the plexiglass and the baffle on the top front.

here is how I made my cheap vent hood:
. went to a recycling type place that has lots of discards from home refurb/remodels and found a large SS kitchen hood
. asked a friend to cut SS sheet metal back/sides (1 large piece bent into shape).
. stood the back/sides piece on my table and mounted the hood to the studs at the right height to meet the back/sides
. used aluminum tape to seal the back/sides piece to the hood piece
. had a contractor mount & wire a free exhaust fan (he had leftover from restaurant remodel) and small amount of ducting
. voila
