My experience is that a random hot air station can get the job done, but what you miss is confidence that the set temperature point is accurate, reliable construction, access to customer support if you have a problem, usual concerns you get with cheap (which inevitably means sourced from China) gear.
I am having to deal with that this week, I bought a cheap hot air station a few years back, it stopped working, found the usual bulged capacitor culprit in a switching regulator circuit. Found out that the construction was the biggest pile of garbage I had ever seen. Had to unsolder a connector just to get the PCB out of the chassis, had to unsolder a large resistor to get access to the capacitor pins to change. I was tempted to just throw it in the trash and buy something different, but that goes against my cheap frugal nature.
