Gas powered soldering irons??

Id second that, save a bit more and buy a temp controlled solder station.
You will wonder how you managed before with a basic iron.
Soldering is so much easier with a constantly controlled temp at the tip.
I bought a cheapish one in a sale at Maplins for about £45.00 and its good enough to make a difference.

I use gas soldering irons only when working on my motorcycles or cars as the convenience of not needing a power supply outweighs the lack of control and generally the sort of soldering on vehicle electrics isnt as demanding of accuracy as electronic projects.
and thats a very good quality Blue Point one from the SnapOn tool van that used to come round when I worked on bikes. Its lasted me over 20 years.
