Roger: Keep your eyes open at the local thrift store and pick up one of the larger toaster ovens.
They work well and once you get them set just mark the settings on the dial as the temperature markings are not that accurate.
Large toaster ovens are cheap as chips as you guys say and a large one is usually around 20 to 25 here at the local Value Village.
Same set up with rods and a frame and NOT SHMBO good baking pan.
Just take it to the garage or outside when baking.....
