Hi, I just love to cook PERIOD - pizza, bread, cake, etc. I want to put in my oven something that 1. won't damage it. 2. Is easy to keep clean or cleans easily and 3. I "can" take it out for baking that isn't the best with bricks. I haven't tried baking cakes or heard of baking cakes with bricks/stones in the oven, so I'm not sure on a permanent insert.
I know reviews are mixed on the HearthKit and it's not available any more and was pricey, but the nice thing about it was that you could REMOVE it quite easily. So, what's the alternative?
My oven is electric and is about 21" wide and is a self-clean (if that matters). Suggestions? I've scoured the site and now I'm all confused on what's safe and what's good, stone, or bricks, glazed or unglazed and so on!

I just want something that my husband won't roll his eyes at, is easy to get my hands on, and VERY IMPORTANT, safe!!!
