So please be not quick to mark this question a duplicate.
My question is this.
I am going to buy a new microwave oven for use in a summer camp where a lot of people are around preparing food and kashrus problems seem likely to arise.
Is there some sort of oven which I can buy, as to which there is a wide consensus that includes Chabniks, that kashering is needless or easy? If so, can you actually recommend brands and models that fill that bill? I would gladly consider any comparable sort of cookery, such as a toaster oven, if that offers any advantage.
