There is also a "boost iron" that I think liveforphysics posted a link to in a recent thread. I don't remember the thread but I saved the link in case I have money sometime for it; it sounds like an excellent iron for the way I work.

I am currently using a Velleman VTSS5 bought a couple of years or more ago at Fry's Electronics for around $40 I think. It's ok, I guess, but the threaded tip holder that was swaged to the cylinder holding the heating element is no longer swaged to it.
I think that lasted about 4 or 5 months before it started to be a little loose. It makes it impossible to tighten the tip holder ring (which works itself loose as I work on things) without two pairs of pliers, and one has to be very thin to grip the small width of tip holder that is available between the ring and the cylinder, as that width is slightly narrower diameter than the cylinder and a lot less than the ring.
Then some time ago the LED that shows it's on started flickering and stopped working at all, which almost got me burned a couple of times thinking it was not actually plugged in and on.
The plastic iron holder is supposed to capture and hold the spring the iron sits in, but that broke the first weeks in. Eventually when I was out someplace fixing some stuff on a consulting job I managed to lose the spring because of that, but fortunately had one off an old cable-run for a dog (meant to keep tension on the cable run between two trees)--it just happens to be almost the same size as the original. A couple of twists of bare wire keep it from coming off the plastic holder now.
However, the tip itself has lasted forever, and I tend to forget to turn it off when I am done, especially since the LED doesn't work. I usually have to have it on almost max temperature to do the work I do with it. Often that is desoldering and soldering large capacitors and whatnot from power and ground planes on motherboards or power supplies, to fix things for a little money now and then. I just have to re-tin it a lot. But it doesn't pit or bend, so I'll give them kudos for that.
