dunno. my first ever soldering project was a handwired keyboard. i was popcorning when i finished. it was my first time using a mechanical switch keyboard too. not bad... 2° project, right after finishing the keyboard was soldering a PMW3360 sensor to someone's board from Github. it was a freaking blast on my 40W, 40 BRL (~ 8 USD) solder

i still have it & i'm selling handwired keyboards at a very cheap price (made with it), trying to set a non-profit that sells fair priced handwired keyboards with Vial & aims to teach the basics of electronics for teens... i can't see myself supplying anything more expensive than cheap solders, nor i can see what joy i would get from an expensive solder tool
