There are about nineteen versions of the iPad to choose from. Which choice you make will determine how much you will pay. The iPad Mini starts at $319 for the lowest priced version and the iPad 4 starts at $499 for the lowest priced version. Each version goes up in pricing depending on what type of options you get such as storage space and screen options. There are also refurbished iPads you can get for different prices, usually at least $100 lower than paying for a brand new iPad.
