I've been looking everywhere, and getting more confused. Many posts are a few years old, hoping to get some more recent recommendations on flashes.
Figured, maybe alleviate some of the confusion by asking here. 
Looking for 1 (and eventually a 2nd) flash for my 7D2. General purpose master flash as well as off-camera use and to eventually use 2 (or 3) in a home-studio setting. Will these work similar to the 430 or 580 - i.e., can the camera control the Yongnuo (or similar) flashes remotely - or do I need triggers for these?
Should I be looking at a wifi-flash? Hoping to spend under $200 (for possibly a pair of flashes)
Any specific model recommendations?
There is a 560EX and 565IV used for sale near me for about $60 CAN each.
560 wireless
568 EXII
600 EXIV wireless
There is also a set: 2 560 IV + 560-TX controller for just a touch over $200 (CAN)
