Purchasing a new Home Oven

I am a home SD baker and bake high heat doughs at least 2x/month. My 8 year old Capital Oven went on me. They no longer manufacture the part for my oven. Anyone have recommendations on purchasing a new oven for my house. I am limited to just under 30" wide. Right now I am cooking with propane on with the burners and oven.

Thanks
