Convection microwave oven capable of only 200C
Convection microwaves are a bad solution for baking. In the worst case, you get one which cannot turn off the microwave part, which means you can forget baking at all. In the best case, you get a compromise solution which is not as good quality as a dedicated tool. This is quite independent of the temperature setting. 

If you want to bake, buy an oven. Toaster ovens of the appropriate size and strength (1500 to 1800 watt) do quite well, and are easy to get on a budget. If the dial only goes to 200, that's OK. You won't get optimal results with some breads and pizzas, but for those you need a bigger investment than most home cooks have anyway. 

A microwave is a luxury item with limited usefulness (it doesn't do anything that can't be done with a stove, adds a bit of convenience), but if you want one and have the resources (money and counter space), buy it separately from the oven.
