RE: kalel's post
I'll recommend this unit as well. In the U.S. they are available on Amazon, at Harbor Freight, and Fry's.
It's compact, light weight, very inexpensive, and the one I have has lasted years of use in the field.
My only complaint is that it doesn't have cooling (fan only) mode, so it needs more time to cool before stowing it in your toolbox than some others. Also, the red plastic at the tip can get soft and sag if it is sitting on the bench running, so I recommend turning it off if it's going to sit for more than a moment.
