Soldering Iron....

For me, smaller is always better. I'd get something like this if I didn't want to spend too much. If I need to do something bigger like battery terminal connectors, a small butane torch works just fine.

I disagree, depending on what you are doing

Some of those regulated irons are trouble. The Weller ones have several different series of tips and are a ***** to sort out, and some of them actually had switches in the handles For soldering occasional wire splices and connectors, they are uneeded complications and not reliable.

For the record, I've got several old soldering stations in various states of workability, and never use any of it on automotive or hardware type stuff.
