As a do it yourselfer our oven has also taken a few unintended hits, the last of which resulted in a new oven. So these home projects can get costly, but the stories are always funny at a later point.
Glass would be my preference, and if anybody has a source, please count me in. I just put the large panels back in the door for safe storage. This reminded me that the glass panels don't recess 100% into the door. Is that typical, and is there an adjustment possible?
