I just bought a best by broan insert (liner), it is installed but the hole isnt through the wall to outside yet. Its going out through the upper part of my cabinets. When I turn it on, it blows the cabinet door open! It has variable speed control, but the lights are off, low, high. I have the 42" version, but they make a 48"' which has a double blower with even more cfm. It looks most like the MA from underneath. I did not do a ton of research on my venthood, this one fit the bill with cfm, variable speed control, and price. (I think it was about $900 on ebay) It does have an 8" vent, which is larger than most, and I had to order the exterior vent cover online also, box stores dont stock 8" around here, and the vent cover seems really cheap, it doesnt have a screen in it to keep animals out, I will have to add one. But the vent itself seems good, so far at least. This route you buy the insert and build the hood around it.

Check Walmart, Hobby Lobby, Michels etc Also check in the photo dept making sure they are clear and safe to use.

If you can't find locally, you can order it online at Digging Dog Nursery, Song Sparrow Nursery or Far Reaches Farms.

They look very similar to the Restoration Hardware 'Madeline Collection'. https://www.restorationhardware.com/catalog/category/collections.jsp?cellBackground=false&parentCatId=cat160045&topCatId=cat1840042&categoryId=cat3910336&sale=false
