Thanks for the detailed reply.
So rather than searching for the parts on the first list you linked, could I just buy the simple DIY kit, advanced DIY kit, power supply and remote? Would that be everything?
Also, is the remote control an actual requirement or just something recommended? I was unsure as to whether I could control the device on the hardware its self.
EDIT: Do you think this soldering iron would be okay? It’s the same brand as the one in the video but not the same model: https://www.amazon.co.uk/YiHua-Soldering-Station-Welder-Repairing/dp/B074Z84TDL/ref=sr_1_3/257-9277959-4901744?s=diy&ie=UTF8&qid=1512938907&sr=1-3&keywords=yihua
I couldn’t find the model in the video here in the UK.
