If you are going to stick with a 200A, just make sure you get one with
enough extra space in it for more breakers for future expansion. You
can almost never have too much extra space in there. And over time
stuff tends to get added or put on it's own breaker. If you don't
already have things like your microwave and toaster oven on their own
breakers, as well as all of your appliances on their own, now would be
the time to figure that into the new box.
