Are you looking for a pure toast only oven or something like the one I have shown below. I recommend these smaller ovens that sit on the counter because they have a lot more uses. This De'Longhi 4-Slice Toaster Oven is on the smaller side and does not take a lot of room on the counter. It's also currently on sale at Macy's.

Although it's a little expensive, you might want to get a convection toaster oven. a convection oven will allow you to reheat stuff really really quickly and easily. i looooove my cuisinart

I have had two Delonghi's over many years of time. I say that because I am only on my second one, and it is hardly new. I like everything about it. It warms up quickly, browns evenly, and does an amazingly good job as a mini-oven for baking when you don't really need to heat up a full-sized oven. The brand I would never recommend is Black and Decker, which my mom had. She now also has a DeLonghi, and really loves it.
