A heads-up is to not cheap out too much on the choice of SD card. With a slow card, the SD card will have a much greater chance that data transfer will not be able to keep up with downloading speed, which in my experience causes all kinds of issues.
I'd personally recommend looking for UHS-I U3 and A2SDXC cards. Definitely stay away from A1 cards. I'm really happy with my Samsung EVO Plus, which was cheapish and great. SanDisk Ultra is a no-no, but anything SanDisk Extreme and up seems good.
