Thinking of getting a turbo convection oven, If you have one what do you think of it?

I've only ever seen one before and have never used one. My oven doesn't work and my microwave is shabby and years old. If I get one of these types of ovens can I put things rapped in silver foil in them? will it cook pastry..like an apple pie you get from a supermarket. Does it brown things. Can it toast bread....cheese on toast...act like a grill???? Any comments or criticisms appreciated. I'm single and don't cook alot.
