It is a personal choice of how often you are really going to use it. There are instances of people wanting an oven and then come to find that they never use it. The opposite is also true.
But there are alternatives if you don't have an oven, like a convection microwave oven mentioned by Wiscampsin or my personal favorite the cast iron Dutch oven using charcoal to bake stuff (though we are known to fire up the oven from time to time).
