You owe yourself to use one of the new temperature controlled solder stations. I have weller wes 51. Use a Hakko at work solders little and tanks as well.
Which type you need depends on what you are doing. I have three separate systems, a temp-controlled station for PC board thorugh-hole parts and light point-to-point wiring, a big old industrial iron for really heavy chassis soldering, and the Weller gun for tanks. I use the first a tremendous amount for radio and amplifier work, the second on very rare occasions where I need to solder something to a radio chassis, and the Weller gun for all tank work.
I think the Weller gun is by far the easiest to deal with for tanks. You can do them with just about anything - one of the best tank craftsman I ever knew was Ed Robbert and he use a pretty small pencil iron (uncontrolled, as I recall), but I find it much easier to use the gun. You want a lot of temperature but not tremendous heat, so it will heat in a spot fast, without having to wait and let the heat soak everywhere else.
Torches (with direct flame) are just not a good idea. The torch with the solder head works OK but if you have the big industrial iron and a place to plug it in, it's easier to deal with and much more predictable.
