I have a ordinary modest 30" range. I bought an unfinished wood hood and finished it to match my cabinets. The hood came with a metal liner and recommendations of Broen vent inserts that would fit the hood. Total cost, hood, vent inset, and labor was $1000. I point this out in case you also are doing a modest kitchen. This is not a set up for a fancy professional range. You could not put the wood hood over an existing hood. I have seen online people make hoods to cover existing hoods. These often are made without a liner and strike me as being hard to clean and possibly a fire hazard if mounted too low.

I have a soffit and I ordered an unfinished wood hood (which came with a metal liner) and purchased a vent insert. You will want to find a hood that will be 30" up from your range or stove top to meet codes in most areas. (Not my kitchen)My hood (in my "my pics" idea book) said it could be installed 24 to 30" inches above the stovetop. However, people here say it has to be 30".

I get that you want fancy without the fancy price. I'm a frugal person, myself. However, it seems though that you're expecting others to do all the research for you. That's bad form and as a result, you are getting less than hospitable responses. Do some of the research yourself and post here for opinions instead of expecting Houzers to do it all for you. That said, I have an induction cooktop with a 600cfm XO insert that I bought for about $300 and built the surround myself. It sounds like a jet engine when on the highest setting (a duct issue), and it doesn't look anything like your $5K+ inspiration hoods. Far from it, but I derive great sense of accomplishment and satisfaction by making things myself. JSYK, there is no residential code that requires ventilation, despite what alot of pros here will say. Get a hood if you want to exhaust steam and odors.

I would so have loved to install a remote blower and an inline silencer, but site conditions and rather strict enforcement of building codes made this a no-go. But not for lack of trying. I think my HVAC guy still hates me for all the questions that I asked him about potential solutions :-) And I do agree that fan noise is a good bit of a contributor to the noise of our hood. So, yes, a remote blower would have been some improvement. But I still feel noise from the baffles is a bigger factor. The noise level drops quite a bit if I operate the hood without the baffles installed. On the other hand, I do think that ModernAire installed a rather powerful fan compared to the baffles. Even when configured correctly, the baffles are always noisy. But if I accidentally install them upside-down, then there is a very loud and annoying high-pitched whistling sound. Whenever our cleaning person gets this wrong, it immediately gets noticed. And even if I do everything correctly, at full power the baffles lift up a little bit. That fan is quite something. The good news is, when operating at full speed, the hood works really well and contains the vast majority of cooking smells. For less smelly foods, I can of course turn down power by about 50%, and then the noise is a little better. And the baffles do seem to do their job of removing grease from the air. I need to wash the baffles quite regularly, because of grease that they capture. Fortunately, it's just a quick trip to the dishwasher. So, very easy to do. There is one nitpick with our hood as over time, a little bit of grease pools outside of the baffles in the hood itself; and eventually it drips down in one corner. My work-around is a paper towel that I hide on the inside of the hood. And everytime that I clean the baffles, I also replace this towel. It's a little MacGyver'd, but it does the job.
