A good soldering iron will be enjoyable to use, last a lifetime, and only need the odd tip or sponge replacement.
I still use an ancient Weller WTCPN because it works well for what I do on the bench. Toss in a couple extra styles of tips and no worries.
For the garage and on the go I use a Weller Portasol P2C-ND, It is a handy little butane unit and makes easy work of PL-259 connectors.
I know it can be hard to justify spending $150-$200 for a soldering station if you don't already know what you are missing out on, but it is worth it.
How is your workshop setup going?
