I am looking for the best countertop oven that can bake 12 inch pizzas cookies cakes and roasts in key me know not a big one one that I can sit on my counter!

The best one Will probably not be at Best buy, if you research it. You may want to look on Amazon, I have been in this situation, it's frustrating.Most of them dry out the food, and leave you disappointed. Carefully research it. Good Luck Take a look at Breville, it might be the best one.

Go to Amazon and search for convection oven, counter top. Check the reviews and pick out what you want
