To be honest, most of the time I surf PlayStore on my PC, it will let you "push" apps out to any device registered with your Google Account. Just click "Install" and it will give you a dropdown of compatible registered devices. Just make sure you registered your Google account on the Android box first, otherwise it wont show in the dropdown.

If you dont mind waiting a week or two, I would get this H96Pro, 3gb/32gb for $56
3GB 32GB H96 PRO+ Smart Android 6.0 TV Box Amlogic S912 Octa core WiFi BT4.1 KDO | eBay
If you need it right away, then I would look for either a T96 Pro, or a H96Pro (newer model of the T96), on Amazon. When reading the reviews on Amazon, keep in mind that the H96 is a brand new model, so reviews dated 2016 must be about some other model. The T95Zplus would be my second choice.
I will say that I like the units with 3gb of RAM better, they are snappier. Also it allows you to set a big fat video cache in Kodi if you tweak the
advancedsettings.xml file.
The T96 is my favorite of the 3 that I own. Its quick, and Kodi 17.1 runs well on it.
ETA: after looking at that H96 ebay link closer, I would just find it on Amazon. The $56 price is for 2gb/16gb. You can do just as good with a Amazon Prime shipper.
