And i just see that the pi 2 didn't drop in price still around 40,-
Zero W also a nice option but seems out of stock (of course).
If i remember correct zero can play most of the 700 mb divx files without a problem, navigating through the interface was a bit slow.
Seems to be sufficient for my purposes.
It's a lot of fun and many different project to play around with, i think you wont regret, go for it
