I will only comment on the stainless steels. I don't see a thing wrong with using 430 in this application. The only thing you give up is being able to make a strong weld -- not a concern for a range hood. (By "strong," I mean a structural application.)

Here is a link that might be useful: 430 properties

Try to get inserts with baffle filters, not mesh. You should check out the Independent Hoods' inserts. Independent used to make the hoods for Wolf, until a couple of years ago when Wolf started making their own hoods in-house. On the Independent website, they have a page that compares the features of the Independent, Broan and Vent-a-Hood. I will link it, but you have to go to page 4 to see the inserts comparisons.

People on the Appliances Forum like the Prestige brand (I don't know anything about Prestige), so you should do a search there for threads about it.

Also, MHO is that SS gauge is more important than type of SS finish. Since there will be a motor running and air blowing, you don't want thinner gauge which could rattle more easily. The lower the gauge number, the thicker the SS. Broan uses 430 24-gauge SS, VAH uses 201 22-gauge SS, and Independent uses 304 20-gauge.
