You could say they are medium range units (especially since the models usually recommended are not the very lowest end models of those brands), but the gap between a cheapo from the hardware store and a Hakko is like 10x bigger than the gap from Hakko to the highest end model for a professional PCB assembler. Incidentally I work in aerospace and I rarely see anything in lab besides Hakko 800 series, 900 series, or 200 series (rework station).
