@Spiderwebb I actually have a 3 head version of the Godox set you linked to (from a different EBay seller, that was UK stock and cheaper than the 2 head kit).
I'm certainly nowhere near as experienced as Mike, Gary, Phil, etc. but can make a couple of observations on my usage of it which may help.
The reason I go the 3 head kit, BTW, was my wife 'volunteering' me to provide a 'photo booth' style shoot at my God Daughters Alice themed 16th Birthday party - which we organised at fairly short notice (her dad had passed away from cancer earlier in the year, and her mum was not in a state to be organising a party) - anyway, this left me needing to light a background and subjects in a section of a large lit hall - so 3 lights was the simplest option I thought (I was learning as i went on this one!) - and EBay was the only way to get what I needed in the timeframe.
The heads themselves worked well - exposure was consistent, fired on demand, plenty of power - in fact, my only real criticism of them would be that I would have liked to REDUCE the power a bit more - which the Lencarta Smartflash 3's will offer. This would make it easier to get a balance between the multiple lights.
I did nor use the supplied trigger, as I use a Sony DSLR with a differnt hot show, but my existing radio triggers have a 3.5mm jack output, so worked fine triggering the units - slave mode on them also worked fine (one of my triggers stopped firing par way through the evening, so I simply switched that head to slave, and all worked as before).
The supplied stands are OK, but I'd not want to try them at full height - fortunately I had a couple of much more solid air damped stands, which I was a lot more comfortable with using.
The Godox softboxes seemed fine, but do take a while to assemble / disassemble - I've since acquired a large octabox of the quick assemble 'umbrella' style (Lencarta Profold are of this type) - which is so much easier!
In short - if you can afford to spend a bit more and get a kit from Lencarta (for example), you will be glad you did in the longer term.
The extra on more robust stands, quick assemble softboxes, and greater range of power adjustment will all be things you wish you had it you dont!
