Any guide/recommendation on which headset to buy ?
I kinda want to get back into making amateur VR apps, but by antique DK2 can't test half the shit everyone consider basic features nowadays.
Not really interested in super-high-quality screen or sensors, just looking for a cheap and solid playtesting tool (and not something from faceberg). 
Ideally one that can also do AR stuff, I kinda want to toy with that.

TL-DR: Grandpa codemonkey hasn't updated his VR gear in age, need advice.
