In China we buy second-hand Redmi 2 for 60RMB each (roughly $9.5). Can be bought in quantities. Fully functional with 2GB RAM+16GB eMMC, and battery, touchscreen, WiFi, Bluetooth, camera, and even 4G support. It's not built from scratch like this one, but if you are just looking for something cheap, then this price is insane.
