Buy an iron where you can get (at low cost) a replacement handle.
You will need a fine tip (at a lower tremperature) for a soldering small components such as SMT.
But a fine tip is not a lot of good for soldering wires to connectors or switches, a larger tip and higher temperature is better.
So I have two iron handles, one with a fine tip, the other with a broad chisel tip.
Much easier to swap handles that bits.
