Product review (4 stars): Great value
Whatever your reason is for taking a long, hard look at the cheapest of range hoods, buy this with confidence.  This was a perfect, and attractive replacement for a 20 year old range hood.  My local Home Depot didn't even carry 36" wide, much less offer a range of options.  You will need to buy and wire in a plug, and provide some duct tape to seal to your existing duct, but this thing was a slam dunk.  Having read the other reviews about how light weight the sheet metal is, I got a good chuckle out of a message on the box, warning me not to pull it out of the box by grabbing the middle of the front edge.  Treat it gently at install, and you'll be rewarded with a dirt-cheap but perfectly functional stainless steel hood.
