Getting in late in the conversation, but we bought a combo toaster oven/convection/broiler for the house and love it. (Black & Decker brand). Decided the regular stove oven too big for small items to be efficient. I'm finding I'm using the smaller unit much more than I thought I would and love it, expecially the broiler. Convection comes on automatically with the bake cycle, has pre-heat and you can set timing options, and then goes off automatically when time is up. Also has several pre-settings for various cooking areas. I'm finding it works much better than did the early version of the micro/convection we once owned, and which I hated.
We also carry an electric oven/broiler combo in the mh along with the regular gas stove top and oven. I did not want the micro/convection oven, because of my bad experience with the other. I find this smaller oven useful for the small items, and when we have good power. It is fairly large, and we store it under the bed and only drag it out when we need to. Have had it since before 1994, and it is still going strong. However, if and when it does die, I'll replace it with the Black & Decker toaster/ convection oven/broiler combo, like we bought for the house.
I also conquered the uneven heat in the gas oven in the mh by using an airbake cookie sheet on the bottom of the oven to more evenly distribute the heat. I don't have any more problems that way. Others use baking tiles, bricks, etc.
