Quoted from xamindar:The TS100 is the best soldering iron I have ever used. There are various sellers. Just get one that has the tips you want (or all the tips).

Yeah, the TS100 is pretty darn amazing for what it is. There is open-source firmware that add a few features (like low-temp mode if you put it down for a bit), and loads of people seem to run it off 18v tool batteries. I haven't gotten around to that kind of setup, but it would make soldering in the field even easier.
