I guess it all depends on pricing and how frequently you want to use the tool.
You see if your intent was to mod/build 2-3 sticks, just get an inexpensive soldering iron around 15watts to maybe 20watts that will let you change the iron tips. Downside is that if you buy a “el cheapo” soldering iron it does not come with the soldering station.
What’s the primary advantage of a soldering station? In my opinion, in stick building scenarios, its the speed. You do not need to wait as long when you have a temperature controlled station. The heat up wait is much less. Also the moderately priced Hakko 936 soldering station has a thin pencil iron that is much lighter and also as thin as a pencil for precise handling. Most stations are temperature controlled. If you need to control your temperature for other application, the temperature controlled station is you baby.
I also have the radio shack one but pencil iron is super long and thick - if that matters to you.
The secondary reason for soldering station with full cast metal casing for your iron is if you are clumsy like me. After putting back the pencil into the hakko soldering station (while it was still on) I have touched the iron pencil casing with my hand and forearm nurmerous times. The casing is actually a thick piece of heatsink. I never got burned because of it.
Hope this helps deciding what features to look for when purchasing an iron. All in all, like the members say, just get 15watt but not too high for electronic soldering and that’ll be enough for PCB soldering (enough to melt solder but not enough to burn the PCB and components). :wgrin:
