Thank you Deeageauz. Silly me, I didn't realize they were so pricey.

There are many wood hood ventilators available they do not need to be stainless. Here is a manufacturer that sells both stainless and silver painted inserts. I have not found Broan to be the best. It takes additional work to get them to fit anything.

This manufacturer will not sell direct to retail but they will guide you to a selection and sell to your installer or cabinetmaker. The cabinetmaker has to stain or paint the hood.
