I am planning on installing a range top and already have a micro/convection combination but would like to add a wall oven with good broiler.
I can't claim the best broiler because I haven't compared my broiler to all others but I like my Electrolux and Wolf oven broilers. The Wolf is in a range and the Electrolux is a wall oven. They both have adjustable levels. You might be able to try the Wolf if you can find one live. Ask your dealer.
