Choosing a better-but-still-cheap flash trigger system

After using the old and trusted Cactus V2s system for over 1.5 years, I got tired of the 10m range limitation.

The last drop happened when I was offered the cance to shoot a theather play from the stage facing the audience and the actors.
No way would I risk letting 60+ people and 6 actors see me failing to take a photo because of trigger issues.

Being an amateur,I can’t really justify Pocket Wizards, AlienBee’s Cybersyncs.Even RadioPoppers are a bit over the top .

So I did the research on which are the best and cheapest radio triggers in the market

RF-602 (by YongNuo)

This ended up being my choice .
They are from a Chinese company called YongNuo, with a mainly eBay presence.

All reviews are very positive.
The 100m range,the 2.4GHz and the AAA battery made the choice easy. All other “cheap” alternatives were 10-30m in range.

Receiver: RF-602rx
Transmitter: RF-602tx
