If there is a Fry's near you they usually have at least one model in the store. I looked at some of them from Target--they have the cutest little versions of this--cute, but I don't know how practical. I like mine that if you filled the bowl holds a couple of gallons of water.
Most often I bake bread in my oven, and roast chicken, and reheat frozen things like pizza and flautas. The Nesco roaster has a liner so you can put meat and veggies and such right in the bottom and do big wet dishes or roast dry ones. I bought it after testing my various pans--I can fit a full size muffin tin and a cake pan in it.
