if you're going to get a "pro-style" range with a lot of heat output, like a wolf, you should not get a downdraft vent.

I had a downdraft in our former house. The vent hood required for our new Wolf range seemed to be overly expensive when we were shopping for it and I really kind of resented spending so much for proper ventilation in the midst of all the expenses associated with a new kitchen. However, when our kitchen was finished, I think that DH and I would have to say that the powerful overhead ventilation is really worth every penny and one of the features of the new kitchen that we appreciate and enjoy most. One of those things you wouldn't miss if you'd never had it but really appreciate when you do.

A downdraft is a real compromise - both in terms of the ventilation and that fact that few range manufacturers make them. Get a real hood - there are some that are less intrusive than others.

I just bought a Wolf 30"AG. I went with a Zephyr Hood. 695 CFM for just under $500.00, and not too intrusive.

glass - Is your Wolf 30" in an island? Could you give me some more info about the Zephyr Hood? I couldn't find it on their website. Thanks.
