I have Einsteins, (4) with Cyber Commander and appropriate receivers for the lights. If someone wants to get AB800 or QB1600 then they will need Plus version receivers to be able to do remote power control.
I have CL-180s (2)and CL-360s (2) along with their remote power control.
I have 60EX-RTs (4) and an STE3. They have embedded remote power control.
These are three distinct lighting solutions. Do they overlap, sure. Would I get rid of one since the other(s) replace it in terms of power, size, convenience etc. NO!
Speedlites, Hybrid, Studio Monolights. Each has its strengths.
I appreciate people having limited budgets, and that many on these boards are amateurs or pro-ams. The reality is, if you want to get the best images you have to have the tools that help you. Making compromises on equipment means compromising opportunity for success.
