I don't get the craze with temp-controlled soldering stations. They don't automatically make one a great solderer. I mean I can solder Rebels cleanly and with 100% success rate with my Weller WP35 and eutectic solder.
I too never understood the higher costs of soldering station. I used a 15w Hakko soldering iron & Weller 35w iron for years. Then I started using the Hakko 936 at my work I got hooked.
Soldering stations heat up instantly. No more waiting around till I get old for my damn iron to get hot especially having to solder just 2 connections & that's it. They also keep the heat consistent which regular soldering irons do not. My nicer irons seem to held the heat ok but not nearly as good as my 936.
My Hakko 936 is also ESD safe. ESD is an issue & just because you don't see it or feel static discharge it is there. I work a computer/laptop repair depot. ESD safety is highly emphasized. When customer like Sony, Gateway, NEW (Walmart, Office Depot), Assurant (Circuit City, COMPUSA), Warrantech (Microcenter), to name a few, come in ESD safety is one of the major things they look for.
ESD damage may have never happened to you & probably may never will if you just solder wires only. I now practice ESD safety to some extent. I used to roll my eyes & always say yeah right, ESD damage never happens. But it does.
Some may benifit from a Solder station, some may not. If you do a lot of soldering I highly recommend one.
I can see how it could be easier to have a nice soldering station but would you still be able to do under dash soldering with one of those?
When I worked under the dash & as a mechanic, my trusty Weller P2KC did the job just fine.
