I will be a college student soon

That means moving furnishings back forth between home
and apartment at school

I will be an adult college student so living alone in
apartment... NOT in dorm

Should I shun buying a bigger heaver more expensive
combo convection microwave over say a cheap reg
microwave and toaster oven?

Will the two cheaper units (toaster oven, reg
microwave)..... do everything a combo oven will do?

You see the combo ovens are bulkier and heavier as
well...so don't want to have to haul that around if
possible

Advice?
