I'm looking at Quantuum 600 ws with external battery (check on ebay) to purchase soon, it's pretty cheap, have good reviews and it's possible to work on normal power source and battery, great for outside shooting


look also for used ones, I have ancient Multiblitz around 30 years old, 600 ws can still do 500 flashes without stopping
