Using a cheap soldering iron is not even remotely as dramatic as you make it out to be though? If you're working with expensive parts, sure you want your equipment to match, but a beginner won't be doing that. A beginner will have a 555, a few resistors and two airwires and honestly you could solder that with practically anything.
I think there are some people in this thread which started soldering before soldering irons with temperature control were the norm. It makes a huge difference indeed, but now practically all have it and they are cheap.
And since I didn't see it mentioned I recommend starting with leaded solder (and good ventilation always).

No, that's like saying "buy the gear that doesn't crush your genitals for cycling first".
I don't think you understand just how shitty experience is with the cheapest soldering irons
