A solder iron/station is something you buy only once or twice in a lifetime and like any tool it pays to buy the best you can afford.
I used to maintain about a hundred of the Weller stations I mentioned and those irons did thousands of joints a day, 5 days a week (and you could NEVER get the buggers to turn them off!) A tip would probably last a month with care, other parts a year or so. Cheaper kit would have been failing daily.
For soldering a few cables say, once a month a $100 station will likely last a decade or more (mine has)
Tip: Get some 60/40 Lead solder if you can (well you CAN if you look!) This is easier to use for the inexperienced and in any case some ancient cables/connectors cannot stand Pbfree temperatures. Do not be concerned about Lead, bit hysterical IMHO. Just do not eat,drink, smoke, solder and wash hands well after.
