Can u get iphone 5 for cheap?

Between Verizon, sprint, and att, what is the cheapest plan for apple iphone 5. I don't need many talk minutes(lowest amount available) for txt i guess unlimited would be nice(if not 1, 000 or more) and for data i want at least 2 gb. For the info i just gave, would it be cheaper to have 2 individual plans or a family plan. Also rate how good the survivce is and is there are any deals going on with any of the companies.thanks.
