Product review (4 stars): Best 42" hood for the money
When redoing our kitchen, I didn't think about the range hood when we bought a 40" range.  Everything on the market was super high end and very pricey.  This was cheap, and seemed like what we needed.

Installation wasn't too bad... the unit comes with a square-vent damper.  I ordered a round vent damper to match existing duct work.  The electrical connection is simple enough.  If you've ever switched out a light fixture or switch, you can manage this.

After installation, I found the vent to be a little noisy, but no more than any Broan/Nutone vent.  The variable speed fan mitigates this noise... for instance, if I have it on low while my range is self-cleaning, it is barely noticeable.  If I'm running it on high while searing steaks, it's nosier.  My wife leaves the lights on pretty much all day, so those have worked without a hitch.  The stainless is easy to clean, and I haven't dinged it yet.  All in all, a pretty good, basic range hood for a decent price.
