As @livramax said, you can make them easily enough, but I bought a pre-programmed 32GB microSD from ebay USA for under $40 for 32GB - absolutely hassle free - just put the card in! type goo.gl/PSKOx into your address bar and it will take you to the ebay pages. I think I saw them on Amazon too, or you can get them for twice the price at

Absolutely no cons that I can think of. So far.

Loving everything about it once past learning Android - which most people are familiar with from their phones already - but I don't have a mobile.
