Weller wouldn’t make anyone using Hakkos feel like missing anything, it’s among the top 5/6 historical brands in the world. I’m sure you’ve made all your evaluations already, but in my opinion that station is even too much for repairing small smartphones boards, you’d be able to get more than enough of what you will need with a much cheaper soldering station, for even less than half. Just have a further look around if you please and maybe explore other top brands products too, like Pace, Metcal-Oki, Ersa, just to name some. Also consider especially on iPhones with a very high component density you’d be using more hot air than an iron..just my 2 cents..
