Another thing that needs to be considered when looking to purchase an oven for your kitchen is the space where it will be located. Some ovens can be installed in a wall, others under a counter and there are those that are part of a traditional stove/oven combination unit. Then other people will look at just how easy the oven will be to clean. A standard oven will have to be cleaned the old fashioned way (using oven cleaner, scrubbing pad and a good deal of elbow grease). However, if you want you could purchase self cleaning ovens which are provided with a super high temperature setting which is used when the oven is empty and the door is locked.
