Hands down for a gooood cheap FPV drone for just play or anything you can think of. I recommend Air Hogs DR1 FPV drone for $70 after taxes at Walmart. They’ll have it listed for $100 in stores but you can still price match their own website.

My personal opinion for devices on WiFi connection for the FPV feature I’d say have been the iPod touch 6gen out of the devices I’ve tried from samsung galaxy 3s, galaxy emerge and some LG phone.
The 2.4ghz controller gives you more control over a drone rather than only Wi-Fi app control. Two speeds on the DR1, beginner and advanced. I strongly recommend beginner (speed 1) if you aren’t used to high speeds on RC vehicles and are new to drones.
