I'm looking at installing a Caldera 36" cooktop. That means I need to upgrade my venting to accommodate all the heat.

There is a cabinet over the cooktop so I need an under mount vent.

I've found the Imperial 3000 slide out vent that seems to be fairly quiet and moves 600 cfm.

Has anyone used one of these or another slide out hood?
