Yes, it's definitely worth paying for the Weller WESD51 or its analog version.

Any decent iron will get the job done, but the Weller station is dependable and well designed. It gets hot fast and keep temperature even when faced with larger solder joints like those on your XT60 connectors, and you can get small tips like the Weller ETO for tight spaces like pin headers on your FC.

I've used the Hakko soldering station as well, and though it works just fine, I was a bit annoyed that it takes several button presses to change the temperature (you have to cycle through each decimal place), but the Weller simply has a knob. To me, this was a huge design failure that interrupts my work when I need higher or lower temps.

These are both good the analog one is s bit cheaper bit I think is a solid kit, keeps consistent temp very well and heats up extremely quick... 500degrees in about 20 seconds from dead cold
